SWBAT: Identify congruent figures Describe congruence transformations. Use
theorems about congruence transformations.
Lesson 4-4
Do Now:
Two geometric figures are CONGRUENT FIGURES if and only if there is a rigid motion or
a composition of rigid motions that maps one of the figures onto the other. C ongruent
figures have the same size and shape.
SWBAT: Identify congruent figures Describe congruence transformations. Use
theorems about congruence transformations.
