Question
Draw a line AB. Take a point P outside it. Deaw a line passing through P and perpendicular to AB.
✓
Answer
Steps for construction:
- Draw a line AB.
- Take a point P outside AB.
- With P as the centre and a convenient radius, draw an arc intersecting AB at M and N, respectively.
- With M as the centre and radius more than half of MN, draw an arc.
- With N as the centre and the same radius, draw an arc cutting the previously drawn arc at Q.
- Draw PQ meeting AB at S.
