Answer 1

For this problem, you will want to use the SSS postulate which is the Side, Side, Side theorem. This means that if you prove three sides of two triangles congruent, then the triangle is congruent. You already know that two sides are congruent, so use the reflexive property and prove DB congruent to DB

Explanation:

Answer 2

Triangle ADB is congruent to triangle CDB because Line BD=BD which represents the reflexive property Theorem . The Given piece in the diagram shows that all outer sides of the triangle are congruent to each-other. If 3 sides of one triangle are equal to all sides of the other triangle, then both are congruent to each-other because LL congruence theorem.
