Answer:

∠c' and ∠c'' are complementary angles

Step-by-step explanation:

Since [tex]A\widehat{D}C \: + \: B\widehat{D}C[/tex] form a straight angle, then

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

Since the [tex]\overline{DC}[/tex] is perpendicular and bisects ∠C

∠c' and ∠c'' are complementary angles
