By the AA Similarity Postulate, ∆MNO ~ ∆QPR. An equilateral triangle with sides 21 cm and a square with sides 14 cm would not be similar because they are different shapes. two sides are proportional and included (inside) angle is congruent, then the two triangles are similar. If 3 angles of 1 triangle are congruent to 3 angles of a 2nd triangle, then triangles are similar.

Terms in this set (19) Similar Figures. We can find out or prove whether two triangles are similar or not using the similarity theorems. If two sides and the included angles of one triangle are congruent to two sides and the included angles of another triangle then the triangles are congruent. If two legs of one right triangle are equal to two legs of another triangle, then the two right triangles are congruent. if 3 angles of one triangle are congruent with the angles of the 2nd triangle, then the triangles are similar.
