geom 8.2 flashcard

Front

What theorem can be used to prove that \( \overline{RN} \cong \overline{RN} \)?

Back

Reflexive Theorem: A segment is congruent to itself.

Front

What postulate proves these triangles congruent?

Back

SAS (Side-Angle-Side) Postulate.

Front

What does SAS stand for?

Back

SAS stands for Side-Angle-Side.

Front

Identify the correct triangle congruence theorem: ASA, AAS, SAS.

Back

ASA (Angle-Side-Angle) Theorem.

Front

Name the postulate that makes the triangles congruent: SSS, SAS, AAS, Not Possible.

Back

SAS (Side-Angle-Side) Postulate.

Front

What is the SSS postulate?

Back

SSS stands for Side-Side-Side; if three sides of one triangle are congruent to three sides of another triangle, the triangles are congruent.

Front

What is the AAS theorem?

Back

AAS stands for Angle-Angle-Side; 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, the triangles are congruent.

Front

What is the HL theorem?

Back

HL stands for Hypotenuse-Leg; it is used to prove the congruence of right triangles.

Front

What is the difference between SAS and ASA?

Back

SAS requires two sides and the included angle, while ASA requires two angles and the included side.

Front

What is the definition of congruent triangles?

Back

Triangles that have the same size and shape; their corresponding sides and angles are equal.
