Question 83
Bisect ∠XYZ in the given figure.
Steps of construction are as follows:
Step I: With Y as a centre and using a compass, draw an arc that cuts both rays of ∠Y. Label point of intersection as A and B.
Step II: With A as centre, draw (in the interior ∠Y an arc, whose radius is more than half the length AB.
Step III: With B as centre and the same radius draw another arc in the interior of ∠Y. Let the two arc intersect at D. Join YD. Then, ¯¯¯¯¯¯¯¯¯YD is the required bisector of ∠XYZ
