In the diagram, AB=BC=CD=DA. prove that triangle ADB is congruent to triangle CBD.

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

step-by-step explanation:

first, eliminate the parenthesis:
