Congruent Angles

Students will review the characteristics of congruency and rigid motion and employ the use of that knowledge while examining various triangles.

Students will examine triangles in order to determine congruency.
Students will connect congruency to characteristics of rigid motion: translation, rotation, reflection, and glide reflection.
