Circle Geometry: Circles with Tangents and Inscribed Angles

The video tutorial explains how to solve a geometry problem involving a circle with center O, tangents, and angles. It covers calculating angle AOC using properties of tangents and radii, and then finding angle ADC using circle theorems. The tutorial emphasizes understanding the relationship between angles at the center and circumference, and provides a step-by-step solution with a focus on key points and marks allocation.

Describe the steps taken to find the angle ADC in the problem.

Why is it important to identify the angles in a kite shape when solving for missing angles?

What is the significance of the statement 'the angle at the center is always going to be twice the angle at the circumference'?
