one right angle no sides congruent?

Then none of the angles are congruent either. :) It's just a right triangle.....

For an arbitrary angle, no.  There is an interesting algebraic proof to show that it is not possible to trisect an angle with a straightedge (no markings) and compass alone through the construction of a field.  Now it is obviously possible for certain angles such as the right angle to be trisected.  However, the subset of angles which can be trisected has measure 0 in the set of all possible angles (countable in an uncountable set).\n\n(See source below for more.)

Well, a circle does have a side.  It is a continuous set of points that are all equidistant from a common point, thus giving it one side.

just a piont of view, but normally to divide something symmetrically you have to do it at the widest piont along the centre line. where as assymetricaly is off the centre line at a narrower piont and therefore not a symmetry,this only applies to poloygons and symmetric shapes.  hope this helps

by the number of sides and angles

I have yet to find such a site that is not oriented to one side or the other.\nSo take what you read on the sites in these links with a grain of salt. Most of them a BIG GRAIN!

Not all triangles are congruent.

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

well, right angles will always be similar, bcuz they r all 90 degrees. however, many triangles r different. try measuring their corners w/ a protracter 2 find out if they r alike.

See the picture:\n\nhttp://mudandmuck.com/str2/sin&cos.jpg\n\nThe two triangles in the picture are equivalent.  (Same angles, and one side of each we know to be the same (hypotenuse=1), so all the sides have the same absolute length, only their signs are different.)

There are three cases:\n1) Side-Side-Side (SSS)\n2) Side-Angle-Side (SAS)\n3) Angle-Side-Angle (ASA)\nNote that Angle-Angle-Angle (AAA) does not guarantee two triangles are equal (congruent).  It does guarantee that they are similar.\nAlso, Angle-Angle-Side (AAS) does not mean the triangles are congruent.

Hi. Don't you hate these? OK you have an unknown angle. Call it a. You have a complement, c, which is 90-a. c=3a-10. Any help?

If the sides are parallel then these angles will be equal.

The direction (angle) of |u| and |v|?

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

Add all sides together

for it to be a triangle the angles have to measure to 180, so if you have a 90 degree andlge off one, you could subtract 90 from that, take the remaining 90 and work with that, since you know your need a 1:1 of the legs , then you know you need an equal angle.. angle has to equal 90/2... and thats where i get stumped...\n      gl
