Question

draw a circle of 3 cm and show Central angle in it and measure the central angle​

Answer 1

Answer:

Draw a circle of radius r=3.5cm

Take a point P on the circle and mark a chord of length <2r and join PQ and also join P and Q with center O

Take any point S on the major sector and join S with P and Q

Taking OP and OQ as base, draw perpendiculars from P and Q respectively.

These perpendiculars meet at T

From measurement it is observed that

∠POQ=2∠PSQ
