## Properties Of Circle: Definition, Common Terminologies, Equation & Circle Formulas

In Euclidean plane geometry , a tangent line to a circle is a line that touches the circle at exactly one point, never entering the circle's interior. Tangent lines to circles form the subject of several theorems , and play an important role in many geometrical constructions and proofs. Since the tangent line to a circle at a point P is perpendicular to the radius to that point, theorems involving tangent lines often involve radial lines and orthogonal circles.

X, Y and Z are points on the circumference of a circle, centre O. And a part of the circumference is called an Arc. A line that "just touches" the circle as it passes by is called a Tangent. Find the radius of the small circles.

Measurement and Geometry : Module 26 Years : PDF Version of module. Most geometry so far has involved triangles and quadrilaterals, which are formed by intervals on lines, and we turn now to the geometry of circles. Tangents are introduced in this module, and later tangents become the basis of differentiation in calculus. The theorems of circle geometry are not intuitively obvious to the student, in fact most people are quite surprised by the results when they first see them.
