The two triangles are similar according to AA rule. option A.
Are the triangles similar?
Angle-Angle similarity theorem states that two triangles are similar if the corresponding angles of both triangles are equal.
Side-Side-Side Similarity theorem states that if the three sides of a triangle are in proportion to the three sides of another triangle, then, they are similar.
Hence, the triangles are similar based on Angle-Angle similarity theorem.
