Common Tangent to Two Circles – Direct and Transverse

Here you will learn common tangent to two circles i.e direct and transverse common tangents to two circles. Let’s begin – Common Tangent to Two Circles Let two circles having centers \(C_1\) and \(C_2\) and radii, \(r_1\) and \(r_2\) and \(C_1\)\(C_2\) is the distance between their centres then : (a)  Both circles will touch : …

Diameter Form of Circle – Equation and Examples

Diameter Form of Circle Equation The equation of the circle drawn on the straight line joining two points \((x_1, y_1)\) and \((x_2, y_2)\) is (\(x-x_1\))(\(x-x_2\)) + (\(y-y_1\))(\(y-y_2\)) = 0. This is known as diameter form of circle. where \((x_1, y_1)\) and \((x_2, y_2)\) are coordinates of two ends of diameter of circle. Note – If …

General Equation of the Circle – Formula and Examples

What is a Circle ? A circle is the locus of a point which moves in a plane in such way that its distance from a fixed point(in the same given plane) remains constant. The fixed point is called center of circle and the constant distance is called radius of the circle. The general equation …
