MATHS - Geometry - Circle Theorems Part 3

The video tutorial covers the intersecting chord theorem, explaining that when two chords intersect inside a circle, the product of their segments' lengths is equal. It then introduces secant lines, which intersect a circle at two points, and explains the intersecting secant theorem. The video concludes with a review of nine circle theorems and mentions related concepts like parallel line angles and isosceles triangles.

Can you list the nine theorems related to circles mentioned in the video?

What other geometric concepts should be kept in mind alongside circle theorems?
