What is the definition of congruence in geometry?

Back

Congruence in geometry means that two figures have the same shape and size. This can be shown through congruence statements such as ∆A ≅ ∆B.

Front

What does the symbol '≅' represent?

Back

The symbol '≅' represents that two geometric figures are congruent.

Front

What is the Angle-Angle (AA) criterion for triangle similarity?

Back

The AA criterion states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

Front

What is the Side-Angle-Side (SAS) criterion for triangle congruence?

Back

The SAS criterion states that if two sides of one triangle are congruent to two sides of another triangle and the included angle is congruent, then the triangles are congruent.

Front

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

Back

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

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always congruent.

Front

What is the Reflexive Property of Congruence?

Back

Front

How can you determine if two triangles are congruent using the information given?

Back

You can determine if two triangles are congruent by using congruence criteria such as SSS, SAS, ASA (Angle-Side-Angle), or AAS (Angle-Angle-Side).

Front

What does it mean if two segments are congruent?

Back

If two segments are congruent, it means they have the same length.

Front

What is the definition of a triangle?

Back

A triangle is a polygon with three edges and three vertices.
