Learn the general equation of a circle when the center is at origin and when it is not in origin. Circle equation can be derived using Pythagoras theorem as well. Solve questions at BYJU’S.
First, we need the equation to be in center-radius form (x - x_0)^2 + (y - y_0)^2 = r^2. Then, the center and radius are given by (x_0, y_0) and r, respectively.What is a Circle? In this lesson, we will learn what a circle is, the equation of a circle, the ...
The Equations of an Ellipse Picture a circle that is being stretched out, and you are picturing an ellipse. Cut an ice cream waffle cone at an angle, and you will get an ellipse, as well. And because you are studying algebra, there is definitely an equation for this shape, too. And ...

In algebra, an equation of a line is a form of representing a set of points. These points—in a 2D coordinate system—are also referred to as variables on an x and y-axis. There could also be a third axis if we are considering a 3D system. This set of variables, i.e., x and...
