What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion that states if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a criterion that states if all three sides of one triangle are equal to the three sides of another triangle, the triangles are congruent.

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion that states if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a criterion that states if two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, the triangles are congruent.

What is the missing piece of information needed to prove triangles congruent using ASA?

Back

To use ASA, you need two angles and the included side of one triangle to be equal to the corresponding parts of another triangle.

What is the significance of the included angle in SAS and ASA?

Back

The included angle is the angle between the two sides being considered, and it is crucial for proving congruence in SAS and ASA.

How can you prove triangles are congruent using AAS?

Back

To prove triangles are congruent using AAS, show that two angles and a non-included side of one triangle are equal to the corresponding parts of another triangle.
