**Title: Understanding Circles and Their Components****Definition:**A circle is a simple closed shape consisting of all points in a plane that are at a given distance from a given point, the center.**Components to Identify:**1. **Center of the Circle:** - The center of the circle is labeled as point \( Q \). It is the point from which all points on the circle are equidistant.2. **Central Angle:** - The central angle is an angle whose vertex is the center of the circle, and its sides are radii. In the diagram, angle \( LQN \) is a central angle.3. **Semicircle:** - A semicircle is half of a circle, formed by dividing a circle along its diameter. In the diagram, the arc \( PMN \) represents a semicircle.**Diagram Explanation:**The diagram shows a circle with:- Points \( P, L, M, N, O \) on the circumference.- Line segments radiating from the center \( Q \) to points \( L \), \( O \), and \( N \).- Arc \( PMN \) forming a semicircle.- Central angle \( \angle LQN \).**Conclusion:**Understanding these basic components of a circle is essential for exploring more complex geometrical concepts and problems involving circles.

Circle is the set of all points in a plane which are equidistance from a fixed point. here Q is the center of the circle. Angle made by the Arc to center of circle is called as central angle. ∠PQL,∠PQO, ∠LQO are central angle. A arc which makes central angle 1800 is called semi circle. here arc OPLQ and ONMLQ are two semi circle . chord is line line segment joining any two points on a circle. Here MN is chord of circle . Diameter is the longest chord of the circle. or a chord which passing through the center of the circle . Here LO is the diameter of the circle. Radius is the line segment joining the center of the circle and any point on the circle. Here PQ is the radius of the circle.' thank you
