Congruency & Similarity Review

Front

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same shape and size.

Front

If two triangles are congruent, what can be said about their corresponding sides?

Back

The corresponding sides of congruent triangles are equal in length.

Front

What is the symbol used to denote congruence between two angles?

Back

The symbol for congruence is '≅'.

Front

If ∆ABC ≅ ∆DEF, what can be inferred about angle A and angle D?

Back

Angle A is congruent to angle D (∠A ≅ ∠D).

Front

What is the difference between congruence and similarity?

Back

Congruence means figures are the same shape and size, while similarity means figures are the same shape but may be different sizes.

Front

What does it mean for two angles to be congruent?

Back

Two angles are congruent if they have the same measure.

Front

If two triangles are similar, what can be said about their corresponding angles?

Back

The corresponding angles of similar triangles are equal.

Front

What is the criteria for triangle congruence known as SSS?

Back

SSS stands for Side-Side-Side, which states that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What is the criteria for triangle congruence known as SAS?

Back

SAS stands for Side-Angle-Side, which states that 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.

Front

What is the criteria for triangle congruence known as ASA?

Back

ASA stands for Angle-Side-Angle, which states that 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.
