SSS Triangle Congruence Quiz

What does SSS postulate state?

• If the three sides of one triangle are perpendicular to the three sides of another triangle, then the two triangles are congruent.

• If the three sides of one triangle are proportional to the three sides of another triangle, then the two triangles are congruent.

• If the three sides of one triangle are congruent to the three sides of another triangle, then the two triangles are congruent.
