Question
Construct the angles of the following measurements:
105°

Answer


Steps of construction:
  1. Draw a line segment AB.
  2. Keeping A as the centre and any radius draw an arc which intersects AB at C.
  3. Keeping C as centre and the same radius draw an arc which intersects the previous arc at D.
  4. Keeping D as the centre and same radius draw an arc which intersects arc in (2) at E.
  5. Keeping E and D as centre and radius more than half of ED draw arcs which intersect each other at F.
  6. Join FA which intersects arc in (2) at G.
  7. Keeping E and G as center and radius more than half of EG draw arcs which intersect each other at H.
  8. Join HA.
Therefore $\angle\text{HAB}=105^\circ $
