Question

select the correct answer. based only on the facts in the diagram, which triangle criterion can you use to prove that δabc and δabd are congruent? a. sas b. saa c. asa d. sss

Explanation:

In the diagram, \( CB = DB \) (marked segments), \( \angle ABC=\angle ABD = 90^\circ \) (right angles), and \( AB \) is common. So two sides and the included angle are equal, matching SAS (Side - Angle - Side) congruence criterion.

Answer:

A. SAS
