Intro to Congruent Triangles

Front

What is a congruent triangle?

Back

A triangle that is identical in shape and size to another triangle, meaning all corresponding sides and angles are equal.

Front

If two angles are congruent, what does that mean?

Back

It means that the angles have the same measure.

Front

What is the symbol for congruence?

Back

The symbol for congruence is '≅'.

Front

Name the angle opposite side BC in triangle ABC.

Back

The angle opposite side BC is angle A (∠A).

Front

If ∠S ≅ ∠V, what can we say about their measures?

Back

The measures of angles S and V are equal.

Front

In triangle ABC, if AB = AC, what type of triangle is it?

Back

It is an isosceles triangle.

Front

What does it mean if two triangles are congruent?

Back

It means that all corresponding sides and angles of the triangles are equal.

Front

If ΔDEF ≅ ΔXYZ, what can we conclude about ∠F and ∠Z?

Back

∠F ≅ ∠Z.

Front

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

Back

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 postulate?

Back

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.
