Question

6) Draw a line PQ = 8 cm Take a point R on it. Draw a
line
passing through R and perpendicular
to PQ using a compass
​

Answer 1

Step I: Draw a line PQ and take a point R on it.

Step II: With R as centre and a convenient radius construct an arc touching the line PQ at two points A and B.

Step III: With A and B as centres and a radius greater than RA construct two arcs cutting each other at S.

Step IV: Join RS and extend it in both directions to get a line perpendicular to PQ.

Thus, XY is the line required which is perpendicular to PQ and passes through R as shown in the above image.

Answer 2

Answer:

this is how the figure will look

Step-by-step explanation:

make a line and mark PQ of 8cm

take a point R.

through R make a 90°angle using compass

take point S where the 90°intersects

Join R and S with a straight line
