How do i know if two triangles are similar

WebWhat information is necessary to prove two triangles are similar by the SAS similarity theorem? You need to show that two sides of one triangle are proportional to two corresponding sides of another triangle, with the included corresponding angles being congruent. What additional information is needed to prove that the triangles are similar? WebOct 10, 2024 · Similar triangles are the same shape but not the same size. Remember that if two triangles are both exactly the same shape, and exactly the same size, then they are identical and we say they’re “congruent.” In a pair of similar triangles, all three corresponding angle pairs are congruent and corresponding side pairs are proportional.

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. WebThus, two triangles with the same sides will be congruent. (Note: If two triangles have three equal angles, they need not be congruent. All that we know is these triangles are similar.) …
