Congruent Triangles

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a theorem stating that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What does SAS stand for in triangle congruence?

Back

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

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a theorem stating that 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, then the triangles are congruent.

What does ASA stand for in triangle congruence?

Back

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

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

Front

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

Back

The triangles are congruent by the AAS theorem.

Front

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

Back

The triangles are congruent by the SSS theorem.

Front

If two triangles have two sides and the angle between them equal, what can be concluded about the triangles?

Back

The triangles are congruent by the SAS theorem.

Front

If two triangles have two pairs of equal angles and one pair of equal non-included sides, what can be concluded about the triangles?

Back

The triangles are congruent by the AAS theorem.

Front

What is the measure of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.
