Unit 5 Review Flashcard

Front

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a method used to prove the congruence of right triangles.

Front

What is the definition of congruent triangles?

Back

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

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a method used to prove triangle congruence when 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 method used to prove triangle congruence when two sides and the included angle of one triangle are equal to the corresponding parts of another triangle.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a method used to prove triangle congruence when two angles and a non-included side of one triangle are equal to the corresponding parts of another triangle.

Front

What is the Reflexive Property in geometry?

Back

The Reflexive Property states that any geometric figure is congruent to itself, e.g., segment AB is congruent to segment AB.

Front

What is the purpose of the ASA congruence criterion?

Back

The ASA (Angle-Side-Angle) criterion is used to prove that two triangles are congruent if two angles and the included side of one triangle are equal to the corresponding parts of another triangle.

Front

What additional information is needed to prove triangles are congruent by ASA?

Back

You need to know that the angles opposite the sides are congruent, specifically the included angle.

Front

What additional information is needed to prove triangles are congruent by AAS?

Back

You need to know that one of the non-included angles is congruent to the corresponding angle in the other triangle.

Front

What is the definition of corresponding parts in triangle congruence?

Back

Corresponding parts are the sides and angles of two triangles that are in the same relative position.
