Author:
mtorres1, A B Cron
Lines a and b are intersecting lines. Congruent Angle Theorems: Vertical Angles Supplemental Angle Theorems: Linear Pair Theorems (form straight line): Adjacent Angles at Point E Move one slider at a time, make observations Congruent Angles should be equal in size. The Supplemental Angles/Linear Pairs should add to be 180°.
