what isthree equal angles?

equilangular in a trianle. if a triange is equilangular, it is equilateral, meaning all sides are the same length

pi*(r^2)\n\nIt doesn't matter which unit you use, just make sure you're consistent.

Angles are formed by two rays that begin at the same point or the union of two rays with a common endpoint, called the vertex\n\nThey are measured in \ndegrees (360 = complete circle), \nminutes ' (60 minutes in one degree) and \nseconds " (60 seconds in one minute)

a right angled isosceles triangle\n\nplease give me 10 points now

the base angles are equal therfore each is (180-25deg17')/2\nso each is 155deg43'/2   which is 77deg51.5' which as a decimal is  is 77.8583degrees\n\nNOW circular measure is The measure of an angle in radians.\nThere are 2*Pi radians in 360deg therefore\n1deg = PI/180 rads\ntherefore\n77.8583degrees= 77.8583 times Pi/180 rads\n\ntake Pi as 3.142 and a calculator gives 1.359 rads

Start with a square. All sides being equal and all internal angles being equal (90 degrees), there are four equal sides, each of which contain only two points --> hence, for N = 4, here are four couples of points which do not contain the other two non-coupled points. If they did contain the other point(s), it would not be a square and thus N would not equal 4. Which isn't true.

tanA + tanB + tanC = tanA tanB tanC is true for any non-right angle triangle\n\nrefer the link below . adequately solved

Sorry, I can't see the photo...but:\n\nSOH - sin = opp/hyp\nCAH - cos = adj/hyp\nTOA - tan = opp/adj

All you have to use is the fact that for any triangle, the measures of the three interior angles add to 180 degrees.  So if you have Triangles ABC and DEF, then you know:\nangleABC + angleBAC + angleBCA = 180 degrees, and\nangleDEF + angleEDF + angleEFD = 180 degrees.\n\nIf two angles are congruent, then they have the same measure in degrees.  So, if angleABC is congruent to angleDEF, and angleBAC is congruent to angleEDF, then:\nangleABC = angleDEF, and\nangleBAC = angleEDF.\n\nUsing substitution:\nangleABC + angleBAC + angleBCA = angleDEF + angleEDF + angleEFD\nangleDEF + angleBAC + angleBCA = angleDEF + angleEDF + angleEFD\nangleDEF + angleEDF + angleBCA = angleDEF + angleEDF + angleEFD.\n\nthen simplify by subtracting (angleDEF + angleEDF) from both sides:\n\nangleBCA = angleEFD.\n\ntherefore, the third angles are congruent.

The angles all add up to 180 degrees.\n\nIf you know the lengths of all the sides you can use the "Law of Tangents" to find all the angles.  This is advanced geometry and Trigonometry, so rather than type, I am including a link to a pretty good explanation.\n\nhttp://answers.google.com/answers/threadview?id=38131

:)\nNice trick question.\nYou should mention that the whole 'equations' reads:\n2 times (pi) radians = 360 degrees (measuring angles).\ntherefore (pi) radians equales 180 degrees (half circle)\nBut the number (pi) is same old 3.14......

Skew angle is an angle >180 but < 360\nFor any angle there is a skew angle in reverse side.\nFor example in other side of 120 degree, there is a 240 degree skew angle.

Degrees are a formula came up to give the most accurate results.  Asking why a perfect straight acrossed angle is 180 instead of 34 is like saying Why are there 12 inch's in a foot isntead of 14.  360 degrees is 1 complete revolution in an angle.

SOH CAH TOA...\n\nsin(angle) = O/H\ncos(angle) = A/H\ntan(angle) = O/A\n\nO=opposite length\nA=adjacent length\nH=hypoteneuse length\n\nsooooo...\n\nsin(angle) = O/H = 18/25\n\nso the angle is...\n\nangle = arcsin(18/25)\n\nPlease try to figure this stuff out on your own before resorting to answers... Europe teaches this to their students in like the 6th grade...

Draw a picture of the two congruent sections, which are connected at B. The exact angle between them doesn't matter so long as it's not greater than 90 degrees. You will see that if AD=CD, then angles A and C are equal. So what happens as angle A gets larger and angle C gets smaller? You should be able to see the answer for yourself.

You have to have a right triangle.\nThen you figure out which is side is opposite or adjacent from the angle you need.
