Answer 2

Answer:

∠c' and ∠c'' are complementary angles

Step-by-step explanation:

Since $A\widehat{D}C \: + \: B\widehat{D}C$ form a straight angle, then

$A\widehat{D}C \: + \: B\widehat{D}C=180^{\circ}$ then they are supplementary angles.

Since the $\overline{DC}$ is perpendicular and bisects ∠C

∠c' and ∠c'' are complementary angles
