- A Circle Theorem is a statement about circles that is proved using geometry. It usually involves relationships between the diameter, radius, chords, tangents, secants, arcs, and other elements of the circles.

A circle is a locus of points that are at a fixed distance from a fixed point on a two-dimensional plane. The fixed point is called the center of the circle and the fixed distance is called the radius. In this article, we will explore various circle theorems that are used in geometry for solving different problems.

An angle inscribedacross a circle's diameter is always a right angle: (The end points are either end of a circle's diameter, the apex point can be anywhere on the circumference.) Play with it here:
A tangent linejust touches a circle at one point. It always forms a right angle with the circle's radius.

Circle theorems are properties that show relationships between angles within the geometry of a circle. We can use these theorems along with prior knowledge of other angle properties to calculate missing angles, without the use of a protractor. This has very useful applications within design and engineering. There are seven main circle theorems:
