Review Congruency/Similarity Triangles

Front

What is congruency in triangles?

Back

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

What is similarity in triangles?

Back

Similarity in triangles means that two triangles have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

What does SSS stand for in triangle congruence?

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, the triangles are congruent.

What does SAS stand for in triangle congruence?

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, the triangles are congruent.

What does ASA stand for in triangle congruence?

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, the triangles are congruent.

What does AAS stand for in triangle congruence?

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 a non-included side of another triangle, the triangles are congruent.

What is the Not Possible option in triangle congruence?

Back

The Not Possible option indicates that there is insufficient information to determine if the triangles are congruent based on the given sides and angles.

How do you find the missing length in similar triangles?

Back

To find the missing length in similar triangles, set up a proportion using the lengths of corresponding sides and solve for the unknown.
