Corresponding Angles

Topic

Geometry Basics

Definition

Corresponding angles are angles that are in the same relative position at each intersection where a straight line crosses two others.

Description

Corresponding angles are formed when a transversal intersects two parallel lines. These angles are equal in measure, which is a key concept in proving the properties of parallel lines and solving geometric problems. For example, if two parallel lines are cut by a transversal, then each pair of corresponding angles is equal. This concept is used extensively in geometry to establish relationships between angles and to solve complex problems involving parallel lines.
