 |
| |
and a point Q on a line PQ. |
| |
 |
| |
An angle equal to at Q. |
| |
 |
| |
| (i) With B as centre and any suitable radius draw an arc to cut AB at D and BC at E. |
| |
 |
| |
| (ii) With Q as centre and the same radius, draw an arc to cut PQ at S. |
| |
| (iii) With S as centre and radius equal to DE draw an arc to cut this arc at T. |
| |
| (iv) Join QT and produce it to R. |
