Definition

A circumscribed angle is an angle formed outside a circle by two intersecting lines, each tangent to the circle.

Description

Circumscribed angles are used in geometry to study the properties of tangents and their relationships with circles. They are important in problems involving circle theorems and are applied in fields such as architecture and design, where circular shapes are common. For students, learning about circumscribed angles enhances their understanding of circle geometry and the relationships between angles and arcs, contributing to their overall mathematical knowledge.
