How to constuct a 67 1/2 degree angle?
The below given steps will be followed to construct an angle of 135° and its bisector. (1) ÐPOQ of 135º measure can be formed on a line l by using the protractor. (2) Draw an arc of a convenient radius, while taking point O as centre. Let it intersect both rays of angle 135º at point A and B. (3) Taking A and B as centres, draw arcs of radius more than OC is the required bisector of 135º angle. SO Angle COQ=67 HALF DEGREES
AB in the interior of angle of 135º. Let those intersect each other at C. Join OC.
