Draw a line segment ¯PQ. Take a point R outside the line segment ¯PQ. Through R, draw a line perpendicular to ¯PQ.
Answer:
- Draw a line segment ¯PQ and mark a point R such that it does not lie on the line segment ¯PQ.
- With R as centre and an appropriate radius, draw an arc that intersects the line segment ¯PQ on two 2 points A and B.
- With the same radius as in step 2, draw 2 arcs with centres A and B respectively and mark the intersection of the arcs as point S.
- Join RS, the line segment ¯RS is the required perpendicular line to ¯PQ.
