Congruent triangles practice

Front

What are congruent triangles?

Back

Triangles that are the same size and shape, meaning their corresponding sides and angles are equal.

Front

What is the significance of corresponding sides in congruent triangles?

Back

Corresponding sides are the sides of two triangles that are in the same relative position. In congruent triangles, these sides are equal in length.

Front

How can you determine if two triangles are congruent?

Back

Two triangles are congruent if their corresponding sides are equal in length and their corresponding angles are equal in measure.

Front

What is the symbol used to denote congruence in geometry?

Back

The symbol for congruence is '≅'.

Front

What does it mean if two angles are congruent?

Back

If two angles are congruent, they have the same measure.

Front

What is the relationship between the angles and sides of congruent triangles?

Back

In congruent triangles, corresponding angles are equal, and corresponding sides are equal in length.

Front

What is the Angle-Side-Angle (ASA) congruence criterion?

Back

The ASA criterion states that 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 is the Side-Angle-Side (SAS) congruence criterion?

Back

The SAS criterion 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.

Front

What is the Side-Side-Side (SSS) congruence criterion?

Back

The SSS criterion states that if all three sides of one triangle are equal to all three sides of another triangle, then the triangles are congruent.

Front

What does it mean for two triangles to be similar?

Back

Two triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion, but they may not be the same size.
