CONSTRUCTION OF A CIRCLE

A circle is the path covered by a point which moves in such a way that its distance from a fixed point always remains constant. The fixed point is called the centre and the constant distance is called the radius of the circle. Hence, a circle can be drawn if its centre and radius are known.

Construction: Draw a circle of radius 3.5 cm.

Step 1: Mark a point O on a sheet of paper, where a circle is to be drawn.

Step 2: Take a pair of compasses and measure 3.5 cm using a scale.

Step 3: Without disturbing the opening of the compasses, keep the needle at mark O and draw a complete arc holding the compasses from its knob.

After completing one complete round, we get the desired circle.
