4.Side Angle Side Congruence (SSA)

Explanation:

Two triangles are congruent by SSA if two respective sides and one respective angle are congruent. In this case, ∠ A for both triangles.

5. Corresponding Parts of Congruent Triangles

Since these triangles are congruent by SSA congruence they have corresponding sides: BD and DC. BD and DC are one of the corresponding parts of these congruent triangles sharing the same measure.
