GCSE Secondary Maths Age 13-17 - Graphs: Circle and Tangent - Explained

The video tutorial explains how to find the area of triangle OAP, where line L is a tangent to a circle at point A, and L crosses the X-axis at point P. The teacher draws a diagram to visualize the problem, identifies the right angle formed by the radius and tangent, and calculates the area using base times height divided by two. The tutorial emphasizes understanding the geometric setup and solving the problem without a calculator, highlighting the importance of planning and applying learned concepts.
