Proving Triangles Congruent

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion for triangle congruence where two angles and the included side of one triangle are equal to two angles and the included side of another triangle.

What is the significance of marked congruent angles and sides in triangle proofs?

Back

Marked congruent angles and sides indicate which parts of the triangles can be used to apply congruence criteria to prove that the triangles are congruent.

Can two triangles be proven congruent if only one angle and two sides are marked congruent?

Back

Yes, if one angle and the two sides are marked congruent, the triangles can be proven congruent using the AAS criterion.

What does it mean if triangles cannot be proven congruent?

Back

If triangles cannot be proven congruent, it means there is insufficient information or the criteria for congruence are not met.
