Math 7 - Unit 6 - Day 1 - Congruent Sides and Angles

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning their corresponding sides and angles are equal.

Front

If triangle ABC is congruent to triangle DEF, which sides are congruent?

Back

The corresponding sides are: AB = DE, BC = EF, and AC = DF.

Front

What is the symbol used to denote congruence in geometry?

Back

The symbol for congruence is '≅'.

Front

If side AB is congruent to side AE, what can we say about their lengths?

Back

The lengths of side AB and side AE are equal.

Front

How can you determine if two angles are congruent?

Back

Two angles are congruent if they have the same measure in degrees or radians.

Front

What is the relationship between corresponding angles in congruent triangles?

Back

Corresponding angles in congruent triangles are equal.

Front

If triangle ABC is congruent to triangle NML, what can we say about angle A and angle N?

Back

Angle A is congruent to angle N.

Front

What is the definition of corresponding sides in congruent triangles?

Back

Corresponding sides are the sides that are in the same position in two congruent triangles.

Front

If two sides of a triangle are equal, what can we say about the angles opposite those sides?

Back

The angles opposite the equal sides are also equal.

Front

What is the significance of the SSS (Side-Side-Side) congruence postulate?

Back

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