Question

11/14 - triangle congruence schoology assignment
your friend asks you for help on a geometry exercise. your friends paper is shown to the right. what error did your friend make? explain.
choose the correct answer below.
a. the asa postulate cannot be used to prove the congruence of the two triangles as shown because the included sides between the two pairs of congruent angles are not marked as congruent in both triangles.
b. the asa postulate cannot be used to prove the congruence of the two triangles as shown because the triangles do not have two pairs of congruent angles.
c. your friends paper does not name the triangles correctly for them to be congruent.
d. your friends paper shows that the sas postulate should be used to show congruence because a pair of congruent angles is included between two pairs of congruent sides.

Explanation:

The ASA (Angle - Side - Angle) postulate requires two pairs of congruent angles and the included side (the side between the two angles) to be congruent. In the given triangles, there is no indication that the included sides between the two pairs of congruent angles (if any) are congruent.

Answer:

A. The ASA Postulate cannot be used to prove the congruence of the two triangles as shown because the included sides between the two pairs of congruent angles are not marked as congruent in both triangles.
