Polar Equation of a Circle Polar form of the equation of the circle is almost similar to the parametric form of the equation of the circle. We usually write polar form of the equation of circle whose center is origin. Let’s take a point P(rcosϴ, rsinϴ) on the boundary of the circle, where r is […]

Equation of a Circle when Center is not Origin Equation of the circle when center is not origin. Let P (x, y) are the cartesian coordinate of points on the circle, and (h, k) are the cartesian coordinate of the center of the circle, which is not the origin. Therefore, OP is the radius of […]

Equation of a Circle – General Form The general form of the equation of a circle is represented by x² + y² + 2gx + 2fy + c = 0. x and y are the arbitrary points on the circumference of the circle, and g, f and c are the constants. This general form of […]

Equation of a Circle when the Center of Circle Coincides with the Origin In this tutorial we will learn, equation of a circle when the center of circle coincides with the origin with examples. Equation of a circle with center at (h, k) and radius equal to r, is (x – h)² + (y – […]

Equation of a Circle – Standard Form What is the equation of the Circle? In this tutorial we will discuss what is an equation of a circle formula in standard form and find the equation of a circle with examples. First we know what is a circle ? A circle is a set of all […]

Right Angle Triangle – Definition – Formula – Properties What is a Right Angle Triangle? A right angle triangle is a type of triangle. A right angle triangle plays an important role in trigonometry. A triangle in which one of the interior angle is 90º or a right angle is a right triangle. Right Triangle […]

How to draw a Circle of a Given Radius – Using Compass Circle A circle is a collection of all the points in a plane, whose all points are same distance from a fix point. The fix point is called center of the circle.  We use instruments for drawing a circle, on a paper whose […]
