Question

explaining the sas similarity theorem criteria
what information is necessary to prove two triangles
are similar by the sas similarity theorem?

Explanation:

The SAS Similarity Theorem requires two conditions for two triangles to be similar: 1) one pair of corresponding angles is congruent, and 2) the ratios of the lengths of the two pairs of corresponding sides that form this angle are equal.

Answer:

To prove two triangles are similar by the SAS Similarity Theorem, you need:

1. One pair of corresponding congruent angles.
2. The ratios of the two pairs of corresponding sides forming that angle are equal.
