Category:Triangle Side-Side-Side Congruence

This category contains pages concerning Triangle Side-Side-Side Congruence:

Let two triangles have all $3$ sides equal.

Then they also have all $3$ angles equal.

Thus two triangles whose sides are all equal are themselves congruent.

In the words of Euclid:

If two triangles have the two sides equal to two sides respectively, and have also the base equal to the base, they will also have the angles equal which are contained by the equal straight lines.
