What is the significance of angle bisectors in triangle congruence?

Back

Angle bisectors can help establish congruence by creating equal angles, which can be used in conjunction with other criteria.

What is the SSS criterion for triangle congruence?

Back

SSS stands for Side-Side-Side, meaning if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.
