: 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?

  • 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)
