Dec 17 Core 2 Geometry Congruence Review (Basics to Proofs)

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion for triangle congruence where two angles and the included side of one triangle are congruent to two angles and the included side of another triangle.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a criterion for triangle congruence where two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a criterion for triangle congruence where all three sides of one triangle are congruent to all three sides of another triangle.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence where two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle.

Front

What is the importance of order in triangle congruence notation?

Back

The order of the vertices in triangle congruence notation indicates which angles and sides correspond to each other, ensuring accurate congruence statements.

Front

How can you prove triangles are congruent using the AAS criterion?

Back

To prove triangles are congruent using AAS, you need to show that two angles and a non-included side of one triangle are congruent to the corresponding angles and side of another triangle.

Front

What is the difference between AAA and congruence?

Back

AAA (Angle-Angle-Angle) indicates that two triangles have the same shape but not necessarily the same size, so it does not prove congruence.

Front

What is the significance of marking invisible parts in triangle proofs?

Back

Marking invisible parts helps to visualize and identify congruent segments or angles that are necessary for proving triangle congruence.

Front

What is the relationship between congruent triangles and their corresponding parts?

Back

If two triangles are congruent, then all their corresponding sides and angles are also congruent.
