(i) Draw a line segment AB = 5.8 cm.
(ii) Draw a circle with centre A with radius more than 1/2 AB.
Similarly,
Draw a circle with centre B with same radius which intersect above circle at M and N respectively.
(iii) Draw line segment MN which intersect AB at point O.
On measuring,
m∠AOM = m∠BOM = 90°
