A circle is the locus of all points which are at a fixed distance from a fixed point.There are two kinds of circles - tangent circle and intersecting circle.
Tangent circles: A tangent circle is a circle on which a line is drawn by touching at a point of the circumference of the circle.
Intersecting circles:When two circles intersect at two points it is called an intersecting circles.
Circle properties:1)Circles which have same radii are congruent
2)Equal circles have equal circumference.
There are many more properties of circles which we will discuss next time with diagrams.
