Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape.

Front

What is the AAS rule in triangle congruence?

Back

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

Front

What is the significance of a bisector in a triangle?

Back

A bisector divides an angle into two equal parts.

Front

What does ∠KQB ≅ ∠AQB indicate?

Back

It indicates that angles KQB and AQB are congruent.

Front

What is the definition of triangle congruence?

Back

Triangle congruence means that two triangles are identical in shape and size, which can be proven using various congruence criteria.

Front

List the tests used to prove triangles congruent.

Back

SAS, SSS, AAS, ASA.

Front

What does SSA stand for in triangle congruence, and why is it not a valid test?

Back

SSA stands for Side-Side-Angle. It is not a valid test because it does not guarantee triangle congruence.

Front

What is the SSS criterion for triangle congruence?

Back

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

Front

What is the ASA criterion for triangle congruence?

Back

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