Question

Draw a circle of radius 3 cm and draw its diameter and label it as AC.

Construct its perpendicular bisector and let it intersect the circle at B and D.

What type of quadrilateral is ABCD? Justify your answer.​

Answer 1

step 1: taking centre OC =3cm , draw a circle. step 2: join A and C and draw a perpendicular bisector of AC that cuts the circumference of circle B and D. step 3 : join B and D. step 4 : thus, ABCD is a cyclic quadilateral
