Question

1 which rule explains why these triangles are congruent?

Explanation:

Step1: Recall congruence rules

Congruence rules for triangles include ASA (Angle - Side - Angle), SAS (Side - Angle - Side), SSS (Side - Side - Side), AAS (Angle - Angle - Side).

Step2: Identify given elements

In the two triangles, we have two angles (the marked angles) and the included side (the side with the mark) equal.

Step3: Apply ASA rule

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

Answer:

The ASA (Angle - Side - Angle) rule.
