Question

17 which triangles cannot be proven congruent using the asa congruence postulate?

Explanation:

Step1: Recall ASA congruence postulate

The ASA (Angle - Side - Angle) congruence postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

Step2: Analyze each triangle pair

For the first pair of triangles, we do not have two pairs of congruent angles and the included - side congruent. For the second and third pairs of triangles, we can identify two pairs of congruent angles and the included side between them is congruent.

Answer:

The first pair of triangles cannot be proven congruent using the ASA congruence postulate.
