The SSS similarity criterion says that two triangles are similar if their three corresponding side lengths are in the same ratio. That is, if one triangle …Side Side Side (SSS) If a pair of triangles have three proportional corresponding sides, then we can prove that the triangles are similar. The reason is because, if the corresponding side lengths are all proportional, then that will force corresponding interior angle measures to be congruent, which means the triangles will …SAS Postulate (Side-Angle-Side) If two sides and the included angle of one triangle are congruent to the corresponding. parts of another triangle, then the triangles are congruent.

To calculate a missing side length, we: Write a proportional relationship using two pairs of corresponding sides. Plug in known side lengths. We need to know 3.3. ASA (angle, side, angle) ASA stands for "angle, side, angle" and means that we have two triangles where we know two angles and the included side are equal. For example: If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent. To prove that the two new triangles are similar to the original triangle, we use the ____ triangle similarity criteria.
