Which of the following statement is not true about a circle?
Two points on the circle divide the circle in two parts called arcs of the circle
A circle is a closed round figure
The line segment joining the centre and any point on the circle is called the radius of the circle
The region between a chord and either of its arcs is called the circumference of the circle
The region between a chord and either of its arcs is called the circumference of the circle
The last option is wrong as:
'The region between a chord and either of its arcs is called the circumference of the circle' is not true because the region between a chord and either of its arcs is called a SEGMENT of the circle.
