Draw a circle with centre C and radius 6 cm. Draw a chord AB. Using compass, from the centre O, draw OD perpendicular to AB, where D is the point where the perpendicular from O meets AB. Measure AD and DB. What do you find?

Draw a circle with centre at a point O and radius 5.6 cm. Draw any chord AB. Draw a perpendicular bisector of AB. Does the bisector pass through the centre O ?

Draw a circle with centre O and radius 5 cm. draw a chord CD of length less than the diameter of the circle. Draw the perpendicular bisector of CD. Does it pass from point O ?

Draw a circle with centre C and radius 7 cm. Draw one diameter and one chord. Draw the perpendicular bisectors of both, the diameter and the chord. Where do the bisectors intersect?

Draw a circle with centre at point O and radius 5 cm. Draw its chord A B , draw the perpendicular bisector of line segment A B . Does it pass through the centre of the circle?

Draw a circle with centre at point O and radius 5cm. Draw its chord A B ,\ draw the perpendicular bisector of line segment A Bdot Does it pass through the centre of the circle?

Using ruler and compasses only. Draw a perpendicular from 0 to AB which meets AB in D.

In a circle with centre O and radius 5cm, AB is a chord of length 5sqrt(3)c m . Find the area of sector A O Bdot

Draw a line segment AB=5.5 cm. mark a point P, such that PA=6cm and PB=4.8 cm. from the point P, draw a perpendicular to AB.

Make a point P and draw a circle with centre P and radius 5 cm. Take any point Q on the circle drawn. With Q as centre and radius 3 cm draw another circle. Label the two points at which the circles intersect as A and B. Join PQ and AB. Find the angle between AB and PQ.

Draw a line segment AB = 6 cm. Take a point P above this line segment. Draw a perpendicular to AB through the point P.
