Unit 5 Review (Congruent Triangles)

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a method to prove triangles are congruent by showing two angles and a non-included side are equal.

Front

What is the congruence statement for triangles ∆TUV and ∆EUV if they are congruent?

Back

The correct congruence statement is ∆TUV ≅ ∆EUV.

Front

What theorem is used to prove triangles are congruent if all three sides are equal?

Back

The SSS (Side-Side-Side) theorem is used to prove triangles are congruent when all three sides are equal.

Front

Which of the following is NOT a method to prove triangles are congruent: ASA, AAS, SSA, SAS, SSS?

Back

SSA (Side-Side-Angle) is NOT a valid method to prove triangles are congruent.

Front

What must you state when using the hypotenuse-leg (HL) theorem in a proof?

Back

You must first state that you have right triangles.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a method to prove triangles are congruent by showing two angles and the included side are equal.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that have the same size and shape, meaning all corresponding sides and angles are equal.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a method to prove triangles are congruent by showing two sides and the included angle are equal.

Front

What is the definition of the reflexive property in geometry?

Back

The reflexive property states that any geometric figure is congruent to itself.

Front

What is the significance of CPCTC in triangle congruence?

Back

CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent, used to prove that corresponding angles and sides of congruent triangles are equal.
