Question

use the diagram to identify the special angle pairs. ∠adc and ∠bdc are a pair of complementa acd and bcd. x complementary angles congruent angles right angles supplementary angles

Explanation:

To determine the angle pair for ∠ADC and ∠BDC, we analyze their positions. ∠ADC and ∠BDC form a linear pair (they are adjacent and their non - common sides form a straight line). The sum of angles in a linear pair is 180 degrees. Supplementary angles are defined as two angles whose sum is 180 degrees. Complementary angles sum to 90 degrees, congruent angles have equal measures, and right angles are 90 - degree angles. Since ∠ADC and ∠BDC form a linear pair with a sum of 180 degrees, they are supplementary angles.

Answer:

supplementary angles
