Contents we will be discussing about circles.
Brief introduction about circle including its definition and standard form.

Introduction to Circle

Types of circle distinguished on the basis of their position w. r. t. the two co-ordinate axis and finding their equation using standard form. Basically in this lecture you will learn to use radius and center to find the equation of a circle.

Types of Circle

General equation of a circle and finding radius and centre of a circle using general equation

General Equation of Circle

Parametric form of a circle, equation of a circle with end points of diameter known to us and position of a point w.r.t. a circle.

Parametric Form of Circle, Equation of a Circle With it's End Points Known

Intercept cut off by the two coordinate axis (x and y) on a circle that is its length and procedure of finding the equation of circle which passes through three known points.

Intercept by Axis and Equation of Circle Passing Through 3 Known Points

Intercept cut of by a circle from a given line.
How to find whether a given line cut the circle or not that is its position w.r.t. circle.
And equation of tangent to a circle T=0.

Intercept By a Circle, Position of a Line w.r.t. a Circle and Tangents

Number of common tangents that can be drawn between two circle in all position possible 
Equation and definition of Normal to a circle. 
Angle of intersection between two intersecting circles.
