Question

Draw an angle of 125$°$ and bisect it.

Answer 1

Steps of construction:
1. Draw an angle ∠XYZ=125° with the use of protractor.
2. With Y as the centre and any convenient radius, draw an arc cutting XY and YZ at N and M, respectively.
3. With N as the centre and a radius more than half of MN, draw an arc.
4. With M as the centre and the same radius as above, draw another arc cutting the previously drawn arc at point P.
5. Join PY and produce to W.
Thus, YW is the required bisector of ∠XYZ.
