What is the definition of congruent figures?

Back

Congruent figures are figures that have the same shape and size.

Front

True or False: All corresponding angles in congruent figures are congruent.

Back

True

Front

If ∆LMK ≅ ∆LMT, what can we conclude about ∠K?

Back

∠K ≅ ∠T.

Front

What does the acronym SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a theorem used to prove triangles are congruent.

Front

Which triangle congruence theorem can be used to prove triangles are congruent if two sides and the included angle are known?

Back

SAS (Side-Angle-Side) theorem.

Front

What is the AAS theorem in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a theorem used to prove triangles are congruent.

Front

What is the SSS theorem in triangle congruence?

Back

SSS stands for Side-Side-Side, a theorem used to prove triangles are congruent.

Front

What is the ASA theorem in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a theorem used to prove triangles are congruent.

Front

True or False: Two triangles can be congruent if they are similar.

Back

False; similar triangles have the same shape but not necessarily the same size.

Front

If two triangles are congruent, what can be said about their corresponding sides?

Back

Their corresponding sides are equal in length.
