The geometric property of two angles being equal is called congruence. This means that the angles have the same measure and are therefore identical in size and shape.
To determine if two angles are equal, you can use a protractor to measure their angles. If the measured angles are the same, then they are equal.
Two equal angles are important in geometry because they have equal measures and can help in solving problems involving angles, such as finding missing angles in a shape or determining congruent shapes.
Equal angles and congruent angles are often used interchangeably, but there is a subtle difference. Equal angles have the same measure, while congruent angles have the same measure and shape.
Yes, two angles can be congruent even if they are in different orientations. As long as they have the same measure and shape, they are considered congruent.
