WebTwo triangles are considered to be congruent if all their corresponding angles and sides are equal. Two triangles are considered to be similar if all their corresponding angles are equal and their corresponding sides are in the same ratio. In (i) Δ ABC and Δ LMN, (1) AB = LM, BC = MN, and AC = LN. (2) ∠ A = ∠ M, ∠ B = ∠ L, ∠ C = ∠ N. WebThere are three criteria to determine if two triangles are similar. AA (Angle Angle): If any two of the angles of the triangles are equal, then the triangles are said to be similar. SAS (Side Angle Side): If two triangles have two pairs of sides in the same ratio and the included angles are also equal, then the triangles are similar. WebIf two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.
