Question

part b
what can you say about ∠adb and ∠bdc based on the sum of their angles? how are the angles related?

Explanation:

Assuming points A, D, C are colinear (forming a straight line through D), the sum of ∠ADB and ∠BDC is 180°. Angles that add to 180° are defined as supplementary angles.

Answer:

∠ADB and ∠BDC are supplementary angles, meaning the sum of their measures equals 180 degrees. They form a linear pair (if A, D, C are collinear), sharing a common side (DB) and their non-common sides form a straight line (AC).
