(1) Draw a line and mark a point P on it.

(2) With P as centre and a convenient radius, draw a long arc intersecting at X.

(3) With X as centre and with the same radius, draw another arc to intersect the above arc at Y.

(4) Again with Y as centre and with the same radius, draw another arc to intersect the one drawn in step 2 at Z.

(5) Now with Y and Z as centres and with any convenient radius, draw two arcs to intersect each other at Q.

(6) Join , let PQ intersect the arc at W.

(7) Taking Y and W as a centre and same radius draw two arcs and let them interest at R.

(8) Join PR, Angle RPB is the required angle of 105^o.
