Every circle has unique diameter.
Every circle has unique centre and it lies inside the circle.
The diameters of a circle are concurrent. The centre of the circle is the point common to all diameters.
A diameter of a circle divides the circular region into two parts; each part is called a semicircular region.
The measure of an angle in a semicircle is $……………$
