Answers
Given : angle XAY
To find : Mark P,Q,D,R and B such that AP = PQ= QD= DR = RB
Solution:
Draw a line AX
Using protractor draw angle at A on AX
Draw a ray AY on angle drawn
Using compass take suitable width taking A as center cut line AX at P
Keeping compass width same taking P as center cut line AX at Q
Keeping compass width same taking Q as center cut line AX at D
Keeping compass width same taking D as center cut line AX at R
Keeping compass width same taking R as center cut line AX at B
AP = PQ = QD = DR = RB
