Q2W5 Geo SSS SAS AAS ASA HL CPCTC

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for 'Side-Side-Side', a criterion for triangle congruence stating that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for 'Side-Angle-Side', a criterion for triangle congruence stating that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for 'Angle-Angle-Side', a criterion for triangle congruence stating that if two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, the triangles are congruent.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for 'Angle-Side-Angle', a criterion for triangle congruence stating that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

Front

What does HL stand for in triangle congruence?

Back

HL stands for 'Hypotenuse-Leg', a criterion for triangle congruence applicable to right triangles, stating that if the hypotenuse and one leg of one right triangle are equal to the hypotenuse and one leg of another right triangle, the triangles are congruent.

Front

What is CPCTC?

Back

CPCTC stands for 'Corresponding Parts of Congruent Triangles are Congruent', a principle used after proving two triangles are congruent to state that their corresponding parts are also congruent.

Front

If triangle EFH is congruent to triangle FGJ by SSS, what can be concluded about their corresponding sides and angles?

Back

If triangle EFH is congruent to triangle FGJ by SSS, then all corresponding sides and angles of the triangles are equal.

Front

How can you determine if triangles are congruent using the SAS criterion?

Back

To determine if triangles are congruent using the SAS criterion, check if two sides of one triangle are equal to two sides of another triangle and the included angle between those sides is also equal.

Front

What is the significance of the midpoint in triangle congruence?

Back

The midpoint of a segment divides it into two equal parts, which can be used to establish congruence in triangles by showing that two segments are equal.

Front

What is the first step in proving triangle congruence?

Back

The first step in proving triangle congruence is to identify the given information and the criteria (SSS, SAS, AAS, ASA, HL) that can be applied.
