How many types of circles are there? Explain in detail.
There are three types of circles, and they are as follows:
-
Tangent Circles: when two or more circles intersect each other at one point, then these circles are termed Tangent Circles
-
Concentric Circles: when two or more circles have the same centre but different radii, then such circles can be called Concentric Circles
-
Congruent Circles: when two or more circles have the same radii but different centres, these Circles are termed Congruent Circles.
