Alternate Exterior Angles Date: 06/03/2002 at 15:45:58 From:
S.B. Subject: Geometry definitions Dear Dr. Math I have been
trying to find out what exterior alternate angles are for hours!
My teacher assigned us a vocabulary sheet for geometry, and the
only term I can't find is alternate exterior angles. I know what
an alternate interior angle is, but not an exterior one. I am
completly clueless! Please help, A.S.A.P.! Thanks------ S.B.

Geometry definitions Hi, S.B. Here's a clue, from everyday
English usage: "interior" means "inside", and "exterior" means
"outside". (You may see those words on paint can labels, for
example.) So alternate _interior_ angles are on opposite sides
of the transversal, _between_ the parallel lines, like the pair
of x's and the pair of y's here: \ ---+------- x \y \ y\ x
-------+--- \ Alternate _exterior_ angles are also on opposite
sides of the transversal, but _outside_ the parallel lines: x\ y
---+------- \ \ \ ------
