Geometry of Circles - Tangent Angle (Level 1)

This math topic focuses on the Geometry of Circles, specifically exploring how tangent lines interact with angles within circles. It includes multiple problems (seven total), each requiring the calculation of different angles formed when a line tangent to a circle meets another line or segment. Students must determine the values of these angles, given limited information and a diagram for each problem. This type of exercise helps in understanding geometric properties and relationships involving circles, tangents, and angles, suitable for intermediate level students.
