Question

Draw a line segment AB= 65 cm and CD = 3cm . Also draw a line segment PQ equals to the sum of AB and CD . Draw a perpendicular bisector of line segment PQ .​

Answer 1

draw. long line for 65 cm . mark one point as A and another is B on the both line from A measure three cm an mark C from C measure 3 cm and marked as D. draw line segment of P Q. on same method then. on compass measure 1.5 and draw perpendicular bisector

Answer 2

1. With P and Q as centers, draw arcs on both sides of PQ with equal radii. The radius should be more than half the length of PQ.

2. Let these arcs cut each other at points R and RS

3. Join RS which cuts PQ at D. Then RS=PQ. Also ∠POR=90

∘

.

Hence, the line segment RS is the perpendicular bisector of PQ as it bisects PQ at P and is also perpendicular to PQ. On measuring the lengths of PR=4cm, QR=4 cm Since PR=QR, both are 4cm each

∴PR=QR.
