Question

draw a line segment of 12 length 12cm. draw a perpendicular on it.
​

Answer 1

Answer:

Step I: Draw a line L and take a point P on it.

Step II: Using a ruler and a compass, mark a point Q on the line L, where PQ=12 cm.

Step III: Mark a point Q outside PQ.

Step IV: Now, with O as centre, draw an arc of appropriate radius such that the arc cuts the line at points A and B.

Step V: Taking A and B as centres, construct two arcs such that they intersect each other at C. Join the points O and C.

Thus, OC is the required line which is perpendicular to PQ.
