Circle is the set of points in a plane that are equidistant from a given point. Learn more about circle, tangent equation, chord etc. with the help of solved examples.
A circle is a geometric shape that is a set of points that are all the same distance from a single point. That single point is called the center of the circle, and the line segment that runs from the center of the circle to any point on the edge of the circle is called the radius...
This lesson focuses on defining a circle, presenting its equation in two different forms (standard and general), and giving examples of how to solve problems. Related to this Question What is the center of the circle if the circle'...
The cartesian equation of a circle is, {eq}(x-a)^2+(y-b)^2=R^2 {/eq}. In this expression, the numbers {eq}a {/eq} and {eq}b {/eq} are the x and y coordinates of the circle's center {eq}C(a,b) {/eq}. Meanwhile, {eq}R {/eq} is the rad...
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.
The standard form for the equation of a circle: (x - h)2 + (y - k)2 = r2 The three points will have the same distance - radius - from the center of the circle, (h, k) The distance from (2, 3) to (h, k) will equal the distance from (3, 4) to (h,...
The standard form equation of a circle is (x-h)2 + (y-k)2 = r2 where the point (h, k) is the center, and r is the radius. In this problem, you're given the center, so h=-4 and k = 8. You just need to find the radius. By definition, the radius is the distance from...

I saw at least one jawliterallydrop, which totally made my day. We talked about why it might be a circle, and what that means for these shapes, then I introduce the proper terminology “cyclic quadrilaterals.” (I taught this lesson as an interstitial between my Quads unit and my Circle...
