Congruent Polygons

Front

What are congruent polygons?

Back

Polygons that have the same shape and size, meaning all corresponding sides and angles are equal.

Front

How can you determine if two polygons are congruent?

Back

By checking if all corresponding sides and angles are equal.

Front

What is the symbol used to denote congruence?

Back

The symbol for congruence is '≅'.

Front

If two triangles have two sides and the included angle equal, what can be said about them?

Back

They are congruent by the Side-Angle-Side (SAS) postulate.

Front

What does the term 'corresponding sides' refer to?

Back

Sides in two polygons that are in the same relative position.

Front

What does the term 'corresponding angles' refer to?

Back

Angles in two polygons that are in the same relative position.

Front

If triangle ABC is congruent to triangle DEF, what can be said about their angles?

Back

Angle A is equal to angle D, angle B is equal to angle E, and angle C is equal to angle F.

Front

What is the significance of the SSS postulate in congruence?

Back

If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What is the significance of the ASA postulate in congruence?

Back

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.

Front

What is the significance of the AAS postulate in congruence?

Back

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.
