Chapter 3 - Section 3.2 - Corresponding Parts of Congruent Triangles - Exercises - Page 152: 40

A) Yes B) Yes

A) Now that we are told that H and C are congruent, it follows that line segments DC and EH cannot be extended. Thus, we can conclude that the two quadrilaterals are congruent. B) Since the quadrilaterals are congruent, the corresponding sides are congruent. Thus, we see that DC and EH are congruent.
