#class10circle #importent qus circle #maths A circle is a basic geometric shape consisting of all points in a plane equidistant from a fixed center point.�� This distance is the radius, and the shape has no corners or straight edges.�Key PartsCenter: Fixed point equidistant from all boundary points.��Radius: Line from center to any point on the circumference.�Diameter: Longest chord passing through the center, equal to twice the radius ([d = 2r]).��Circumference: Total boundary length, given by [C = 2\pi r].�PropertiesCircles exhibit full rotational symmetry around the center and reflection symmetry along any diameter.�� They enclose the maximum area for a given perimeter (isoperimetric inequality).�� Equal radii mean congruent circles; the diameter bisects the shape into semicircles.�TypesConcentric: Share the same center but differ in radius, like nested rings.�Congruent: Identical radii and size.�Tangent: Touch at exactly one point.�
