Triangle Congruence Corresponding Parts

The standard focuses on understanding congruence in terms of rigid motions and applying the properties of congruent triangles.

Congruent angles are angles that have the same measure, often indicated by the same number of arcs in diagrams.

Their corresponding angles are also congruent.

The symbol used to denote an angle is ∠.

In congruent triangles, corresponding angles are equal in measure.

We can use the fact that the sum of the angles in a triangle is always 180 degrees.

It means that angle E is congruent to angle A, indicating they have the same measure.

We can assume that corresponding angles and sides are congruent.

Corresponding parts refer to the angles and sides of congruent triangles that match each other.

The legal addition refers to the ability to state that if two angles are congruent, then their corresponding parts are also congruent.
