In mathematics, the definition of congruent angles is "angles that are equal in the measure are known as congruent angles". In other words, equal angles are congruent angles. It is denoted by the symbol "≅", so if we want to represent ∠A is congruent to ∠X, we will write it as ∠A ≅ ∠X.

Congruent angles are two or more angles that are identical to each other. Thus, the measure of these angles is equal to each other.

Congruent angles are angles that have the same measure. The measure of angles A and B above are both 34° so angles A and B are congruent or ∠A≅∠B, where the symbol ≅ means congruent. The sides of the angles do not need to have the same length or open in the same direction to be congruent, they only need to have equal measures.

The definition of congruent angles is two or more angles with equal measures in degrees or radians. Congruent angles need not face the same way or be constructed using the same figures (rays, lines, or line segments). If the two angle measurements are equal, the angles are congruent.

In geometry, two angles are said to be congruent if they have the same measure. In other words, congruent angles are angles that have equal degrees.
