"Two triangles are said to be similar if the measure of three interior angles in one triangle are the same as the corresponding angles in another.
This is one of the way to test the congruency of the triangles. It states that, "Two triangles are said to be congruent, if two adjacent angles, and a side of one triangle are congruent with the corresponding angles and side of the other triangle."
This is one of the way to test the congruency of two triangles. It states that, "If two angles in one triangle are congruence with the corresponding angles in the other triangle, and also if the included sides are congruent, then the two triangles are said to be congruent".
