Question

Construct the angle of the measurement:

1. 135°

Answer 1

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

`∠` HAB = 135°
