Chapter 4 Postulates/Theorems

Question 1

Composition Theorem

Answer 1

The composition of 2 or more rigid motions is a rigid motion

Question 2

Reflections in Parallel Lines Theorem

Answer 2

If lines k and m are parallel, then a reflection in line k is followed by a reflection in line m is the same as a translation

Question 3

Reflections in Intersecting Lines Theorem

Answer 3

If lines k and m intersect at point p, then a reflection in line line k followed by a reflection in line m is the same as a rotation about point p. The angle of rotation is 2x, where x is the measure of the acute of right angle formed by lines k and m
