A circle is a round-shaped figure that has no corners or edges. Ingeometry, a circle can be defined as aclosed shape,two-dimensional shape,curved shape. A few things around us that are circular in shape are a car tire, a wall clock that tells time, and a lollipop. ...
What is a Circle?In geometry, a circle is the locus of points located at the same distance from a given fixed point. The word locus sounds complicated, but it means set of all points on a plane. The fixed point is called center of the circle....
In geometry, the term circumscribe refers to a specific type of figure or shape. To circumscribe means to draw a line or curve around an object so as to completely enclose it. This line or curve is called the circumference of the shape. Let�s take a c
A "unit" circle has a radius of 1. In other words, the distance from the center of the circle to any part of the edge is always 1. The unit of measurement doesn't really matter, because the most important thing about the unit circle is that it makes many equations and calculations m...
I believe that a circle is a curve, mathematically. We talk about "equation of a circle" which defines a curve (the region enclosed would be described by x^2+y^2<r^2). The region inside the curve is a disk (or disc). In our everyday life, however, a circle can refer to both...
In geometry, the incircle or inscribed circle of a triangle is the largest circle contained in the triangle; it touches the three sides. The center of the incircle is a triangle center called the triangle's incenter. How do you find the Incircle of a triangle?
what is the radius?? What is analytic geometry? What is an arc in geometry? Find the point on the sphere x^{2} + y^2 + z^2 = 25. A plane intersects a sphere, forming a circle that has area 24 \pi \space units^2. If this plane is 5 units from the center of the sphere,...
What is the diagonal of a polygon? What are the properties of regular polygons? Is a circle a polygon? What is the minimum number of sides a polygon must-have? Can a number of angles and the number of sides for a polygon be different?
What is an arc in geometry?Geometry:Geometry being a wide concept, includes a huge number of theorems, properties and basics which give shape to various geometrical figures. Thus, to know all about the basics- the building blocks, by the help of which these figures hold their properties, is...
In this article, we cover the most important properties of circles and important circle formulas such as area and perimeter of a circle.
