Draw a circle with centre O and radius 2.5cm. Draw a chord AB passing through its centre. The ∠AOB is:
Draw a circle with centre at point O and radius 5 cm. Draw its chord AB, draw the perpendicular bisector of line segment AB. Does it pass through the centre of the circle ?
Draw a circle with centre C and radius 3.4 cm. Draw any chord ¯¯¯¯¯¯¯¯AB. Construct the perpendicular bisector ¯¯¯¯¯¯¯¯AB and examine if it passes through C if ¯¯¯¯¯¯¯¯AB happens to be the diameter.
