In the given proof, what is the reason for step 1?

• Angles that form a linear pair are supplementary.

• Angles of Equal Measure are Congruent

• Reflexive Property of Congruence

• Definition of a Perpendicular Bisector

Use the Perp Bisector Theorem to DC (hint...find x first and then plug it back in to DC)
