What is the SSS postulate?

Back

The SSS (Side-Side-Side) postulate states that if three sides of one triangle are equal to three sides of another triangle, then the two triangles are congruent.

What is the SAS postulate?

Back

The SAS (Side-Angle-Side) postulate states that 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 is the AAS postulate?

Back

The AAS (Angle-Angle-Side) postulate states 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, then the triangles are congruent.

What is the significance of congruence in triangles?

Back

Congruence in triangles indicates that the triangles have the same shape and size, allowing for the use of corresponding parts in proofs and problem-solving.

What does it mean if two triangles are not congruent?

Back

If two triangles are not congruent, it means that their corresponding sides and angles are not equal, indicating different shapes or sizes.

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

Back

To determine if two triangles are congruent using the SAS postulate, check if two sides and the included angle of one triangle are equal to the corresponding two sides and included angle of the other triangle.
