How do you make various acute angles with just a compass and straightedge?

what you want to do is draw an isosoles triangle with the 2 congruent angles the size you want. \n\nStart with a base with a certain length (use the compas to measure, say 4 inches).  Next determine the midpoint by marking arcs nboth above and below your line from each endpoint using the same compass diameter, then drawing a line through the two intersections.  You now have a right abngle at the midpoint.  You can now determine how tall your triangle must be using the sin table and use your compass to mark the point on the vertical line to complete the triangle with the angle you want.

You have to draw the lines and mark the points.\nIf Cp has a 90 degree angle with the line you just draw and crosses it right in the middle, then you have graphic proof that it is the perpendicular (which means it has a 90 degree angle) bisector (which means that it splits another line in two halfs).

if someone is angry go with sharp angles and inclines. if someone is calm go with smoothe rolling lines. if there solid and steadfast, deep angles with little variation.

Draw a horizontal staight line to be the base of the trapezoid.\nMark a point to be a corner of the trapezoid. Label it A.\nSet your compass to the length of the base.\nMeasure that distance from the first mark and make a second mark on the line. Lable it B\n\nWithout changing the width of the compass, put the point at A and swing an arc above the line. Move the point of the compass to B and swing and arc. Lable the point where the arcs cross C.\n\nDraw the lines AC and BC. You now have an equilateral triangle. The angles are all 60 degress.\n\nSet your compass to the distance of the leg length.\nPut the point at A and swing an arc across AC. Label the intersection D.\nMove the point to B and swing an arc across BC. Label the intersection E.\nDraw the line DE.\nDone.

1. All angles are equal\n2. All angles are less than 180° \n3. Size of each angle = (180 - 360/n)° where n = number of sides

Start with a graph of:\nf(x) = x\n\nThat's a straight line going through the origin with a slope of 1.  It should look like a 45 degree angle if you draw it correctly.\n\nNow to transform this to:\nf(x) = | x |\n\nYou have to think of each value smaller than 0.  Rather than -1, for example, you'll have 1.  Rather than -2, you'll have 2, etc.  This is like "mirroring" the graph that is below the x-axis so that it is above the x-axis.\n\nThis results in a "V" shape.  A slope of -1 down to the origin, then a slope of 1 from the origin.\n\nFinally:\nf(x) = | x | - 2\n\nFor every value that results, you now subtract 2.  For example, x = 0, gives -2, rather than 0.  This is true for every point x, making every point y smaller by 2.  It would look like you shifted the whole graph down 2 units.\n\nSo it would be "V" like before, but it would go down at a slope of -1, cross the x-axis at -2, and continue to (0, -2).  Then it would slope up (m=1) through the x-axis at 2 and continue upward.\n\nYou can go to the first link and type 'abs(x) - 2' in the box.  The resulting graph is shown as the 2nd link.

I take it you are speaking of a normal compass, just one that happens to be very old.\n\nStand still and hold it so it is relatively flat in your hand (I find it works best for me if I hold a compass in my palm).\n\nThe needle should automatically move to magnetic north.\n\nTurn so you are facing the same way the needle points, and you will be facing north, as well. Due west will be directly to your left, south will be directly behind you, and east will be directly to your right. \n\nYou need to have an idea of where the location you are trying to reach is if you want to get there by using a compass, and a map is really helpful. Say that your object lies to the NE of where you are standing. If you are facing north, and east is on your right, then NE is between the two. Find an object in the distance to orient yourself to NE, and begin to move in that direction. \n\nTake regular compass readings, so you know that you haven't strayed off course and begun moving to the north or the east again.\n\nIf you want to learn to use a compass effectively, I really suggest you take some time and go out in the woods. Stay close to where your car is, preferably on a marked trail, so you don't get lost, and practice finding your direction.\n\nCompasses are great, but if you plan on being out in the wild a lot, and need a really sure way of knowing where you are located, I strongly suggest you look into a small GPS (global positioning system) unit. GPS uses satellites to fix your location anywhere on the planet, and for around $100, you can get one that is accurate down to about 10 feet. Many GPS units also have all sorts of neat add-ons so you can mark spots where you saw interesting things, or find spots of interesting locations. \n\nHope this explains it a little for you.

Draw a line.  Set the compass to the distance you want the point to be from the line so the circle passes through the point at the top of its arc.  Draw the circle.  Then draw the same size circle again at another point on the line and connect the tops of both circles.

Turn it any number of degrees!\nMaybe you mean only 0 or 360 degrees, because the 'T' or 't' has no rotation symmetry.

Plot 3 points, connect them with lines. you get a triangle\n\nList most acute (sharp) angle 1st, most obtuse (blunt) angle last, and remaining one in the middle.\n\nIt looks like C will be the most obtuse

If this isn't a math question and you don't want to buy a tool and you don't have a protractor, there should be a leveled board on the ground, and your tilted board should be long enough to reach it. Mark the ground board where the tilted board touches it. Mark a point on the tilted board (the higher it is the more accurate your answer will be), drop a plumb line from there to the ground board, and mark where it touches. Measure the length from the bottom of the tilted board to the upper plumb-line mark (call it "A") and the distance between the two marks on the ground board (call that "B"). The cosine of the angle you want is B/A. Many calculators will give you the angle (using an arc-cosine function).

We can do this 2 different ways.\n\nFirst: Use the Pythagorean Theorem. Since all angles are right angles, the diagonal (measure from corner to corner) is the hypotenuse of the right triangle formed.\n\nBy the Pythagorean Theorem, 10^2 + 10^2 =x^2, where x=diagonal\n\nx^2=200\nx=sqrt(200)\nx=10 sqrt 2\n\n2nd way: use 45-45-90 Triangles\n\nWhen you draw any diagonal in a square, you get a 45-45-90 degree right triangle. This is because the 2 sides are the same, so the 2 base angles must be also. The top is 90, so the others must be 45 and 45 to equal each other.\n\nThe sides to a 45-45-90 right triangle are always in the ratio 1:1: sqrt(2) where sqrt(2) is the hypotenuse.\n\nYou know that the sides are 10 feet. Therefore the hypotenuse is 10 sqrt2 feet

first draw a circle, and then put the star in it w/ the points touching the edge. that divides the circumference of the circle into 5 equal parts. so to find the degree of each one of those section divide 360 by 5 = 72. now look at the angle that is made from the lines from the ends of the individuals sections to the point of the star it goes to, which is the inscribed angle. now that angle which is one of the acute angles is half of its intercepted arc. so that makes 72 divided by 2= 36. so since you wanted to know the measure of all the acute angles and not just one multiply 36 times 5 = 180

if you are asking .. how to sketch an eclipse ... take two verticies (two spots some distance apart left to right on a page) ... and using a compass play with intersecting the radius' of different lengths ... you will find that if you pick the one of equal length as the distance from the vertices ... you will get an intersection of the two radius' from the original vertices ... then playing with the new found radius' ... you will be able to place arcs on the ajoining vertices to creat the other two arcs and blend them together creating an approximate elipse ... a french curve help too

well you can make a pretend display on a real compass, IE when its pointing north make the paper display say whatever direction you want, compasses work by pointing north  http://science.howstuffworks.com/compass1.htm
