Kala - Intersecting Line Properties
Lines a and b are intersecting lines.
Congruent Angle Theorems:
Vertically Opposite Angles
Supplemental Angle Theorems:
Linear Pair Theorems (form straight line):
Adjacent Angles at Point E
Move one slider at a time and make observations. Congruent Angles should be equal in size. The Supplemental Angles/Linear Pairs should add up to be 180°.
