What is Triangle Congruency?

Back

Triangle Congruency refers to the condition where two triangles are considered congruent if they have the same size and shape, meaning their corresponding sides and angles are equal.

What does SSS stand for in triangle congruency?

Back

SSS stands for 'Side-Side-Side', a postulate that states if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

What does SAS stand for in triangle congruency?

Back

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

What does ASA stand for in triangle congruency?

Back

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

Front

What does AAS stand for in triangle congruency?

Back

AAS stands for 'Angle-Angle-Side', a postulate that states 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, then the triangles are congruent.

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

Can two triangles be congruent if only one side is equal?

Back

No, two triangles cannot be congruent if only one side is equal. At least two sides and the included angle or other congruence criteria must be satisfied.

What is the criteria for triangle congruency using SSS?

Back

For SSS, if all three sides of one triangle are equal to all three sides of another triangle, then the triangles are congruent.

What is the criteria for triangle congruency using SAS?

Back

For SAS, if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.
