Short Answer

Expert verified

The triangles are congruent by SAS postulates.

Step by step solution

01

Step 1. Apply the concept of the SAS postulate.

If two sides and the included angle of one triangle are congruent to two sides and the included angle of a second triangle, then the triangles are congruent.

02

Step 2. Check the figure.

Consider the figure.

03

Step 3. Step description.

From the figure, one side and one angle of one triangle are congruent to one side and one angle of another triangle also one side is common to both triangles.

Therefore, the triangles are congruent by SAS postulates.
