We can't use SAS to prove these triangles are congruent because they're not proportional to two corresponding sides.

<h3>How to illustrate the information?</h3>

It should be noted that the SAS similarity criterion states that when two sides of one triangle are proportional to two corresponding sides of another, and when the included angles are equal, the two triangles are similar.

In this case, we can't use SAS to prove these triangles are congruent because they're not proportional to two corresponding sides.
