<h3>What is a circle?</h3>
It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
The radius is the double the diameter.
The longest chord in the circle is diameter.
The angle formed at the centre is known as centeral angle.
Thus, the 1- diameter, 2-inscribed angle, 3-chord, 4-minor arc, 5-central angle, 6-radius, and 7-centre.
