Revolt · Accepted Answer

Rigid transformations preserve segment lengths and angle measures.; A rigid transformation, or a combination of rigid transformations, will produce congruent figures.; In proving SAS, we started with two triangles that had a pair of congruent corresponding sides and congruent corresponding included angles.; We mapped one triangle onto the other by a translation, followed by a rotation, followed by a reflection, to show that the triangles are congruent.

Question 3

We know that segment QS bisects angle TQR because . By the definition of angle bisector, angle TQS is congruent to angle . We see that segment QS is congruent to segment SQ by . Therefore, we can conclude that triangles QRS and QTS are congruent by .
