Question

move points f until you have a triangle. you can also move points a, b, or c from the first triangle to change the size. given three sides of one triangle are congruent to three sides of another triangle, are the triangles necessarily congruent?

Explanation:

The Side - Side - Side (SSS) congruence criterion states that if the three sides of one triangle are congruent to the three sides of another triangle, then the two triangles are congruent.

Answer:

Yes, if three sides of one triangle are congruent to three sides of another triangle, the triangles are necessarily congruent.
