Question

draw perpendicular line of 8 cm​

Answer 1

Steps of Construction:

1. Draw a line segment PQ of 8 centimeter.

1. Draw a line segment PQ of 8 centimeter.2. 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.

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