4.1 Congruenct Sides and Angles

Front

What does it mean for two angles to be congruent?

Back

Two angles are congruent if they have the same measure.

Front

What is the symbol used to denote congruence?

Back

The symbol for congruence is '≅'.

Front

In congruent triangles, what are corresponding parts?

Back

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

Front

If ΔABC ≅ ΔDEF, what can we say about angle A and angle D?

Back

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

Front

What is the relationship between the sides of congruent triangles?

Back

The corresponding sides of congruent triangles are equal in length.

Front

If two triangles are congruent, how many pairs of congruent angles are there?

Back

There are three pairs of congruent angles.

Front

What is the importance of the order of vertices in triangle congruence?

Back

The order of vertices indicates which angles and sides correspond to each other.

Front

What does the term 'corresponding sides' refer to?

Back

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

Front

If ∠E ≅ ∠A, what can we conclude about their measures?

Back

The measures of ∠E and ∠A are equal.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.
