Steps of construction:
1. Draw a line segment AB and produce BA to pint C
2. With center A and any radius, draw an arc which intersect AC to D and AB at E.
3. With center D and E and radius more than half of DE, draw two arcs which intersects each other at F.
4. Join FA which intersect the arc in (2) at G
5. With center G and D radius more than 1 /2 GD draw two arcs which intersect each other at H
6. Join HA
