Triangle Congruence

Front

What is Triangle Congruence?

Back

Triangle Congruence refers to the condition where two triangles are considered congruent if their corresponding sides and angles are equal.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion for triangle congruence.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a criterion for triangle congruence where all three sides of one triangle are equal to the three sides of another triangle.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence where two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.

Front

What does AAS stand for in triangle congruence?

Back

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

If two triangles have two pairs of equal angles, what can be concluded?

Back

The triangles are congruent by the AAS criterion.

Front

If two triangles have three pairs of equal sides, what can be concluded?

Back

The triangles are congruent by the SSS criterion.

If two triangles have one pair of equal angles and the corresponding sides are equal, what can be concluded?

Back

The triangles are congruent by the AAS criterion.

What is the value of x if the angles of a triangle are 30°, 60°, and x°?

Back

x = 90° (the sum of angles in a triangle is 180°).
