Using Circle Theorems: Focus on the Chord Bisector

The video tutorial focuses on chord bisectors and circle theorems, explaining how a perpendicular from the center of a circle bisects a chord. It covers the use of coordinate geometry to solve problems involving chord bisectors, including calculating gradients, finding equations of lines, and determining points of intersection. The tutorial demonstrates how to prove a line is a perpendicular bisector and verifies points on a circle. It concludes with a summary of the key concepts discussed.
