Circle Geometry Course

Circle Geometry Course
from 4 to 360h flexible workload
valid certificate in your country

What will I learn?

In this course, you will develop a thorough understanding of circle geometry, covering core properties, angle relationships, chord theorems, and tangent line behaviour. You will learn to calculate arc lengths, sector areas, and segment areas using both degree and radian measures. The course also teaches you how to apply algebraic methods to circles on the coordinate plane, including deriving equations and analysing intersections. You will build formal proof-writing skills using deductive reasoning, congruence, and similarity. Advanced topics include the power of a point, radical axes, and circle inversion.
