: : why do the angles of a triangle add up to 180*?

: You had me stumped for a while...was ready to bs my way with:
: a straight line has 180 degrees, and to make a triangle, you can
: "fold or bend" that straight line, so the triangle HAS to have them
: 180 degrees...but I knew damn well Mr G et al would have put a
: stick in my spokes with: why has a straight line 180 degrees ?!

: Then it came to me; ARE YOU READY?
: A square or rectangle has 4 right angles, so 360 degrees, right?
: Draw a corner to corner diagonal : that splits it in exactly 2 identical
: triangles, right? So each s'got to have 180 degrees...
: How you like them apples, Joel?

who says a traingle has to have 180^o?

what if I drew a triangle, say, with one vertex at the north pole and interior angle measure of 90^o. then drew each side of this angle south to the equator and let the equator be the third side of the triangle. This triangle has interior angles that add up to 270^o.

• NO WAY! first, you have to prove that a circle = 360 degrees...then that a right angle = 90 degrees! (and is not a left angle). Denis Borris 12:41:03 10/26/02 (0)
