Answer:
Circle is a plane region bounded by by a line that lies at a uniform distance from a fixed point.
Step-by-step explanation:
Circle is a plane figure which is formed by the locus of a point which is at a fixed distance from a fixed point called center and the periphery of the figure is called circumference. The distance between any point on the periphery and the center is called radius of the circle.
Diameter is twice the length of the radius and it is the largest line segment that can be drawn between any two points on the circumference.
Any line segment connecting any two points on the periphery of the circle is called a chord, diameter is the largest chord.
Any line passing through any two points on the circumference of a circle is called a secant.
Any line passing through any one point on the circumference of a circle is called a tangent.
