Question

Construction,Q1 Using a protractor draw an angle angle B-75degree. Draw the angle bisector of this angle.

Answer 1

First draw a line segment of any length, keep your compass at a point on the line segment and draw an Arc of 180 degree with a compass mark angle of 60 degree and keeping a protractor on one end of the line segment draw an angle of 75 degree now keep your compass on the point from where you Mark the angle of 60 degree and extend the ark now keep your compass on the. Where the line of angle of 75 degree is intersecting the arc of 180 degree and extend the ark so that it should intersect with the arc drawn by extending the Ark of 60 degree join the point to one end of line segment or from where u made arc of 180 degree so draw a line joining that point it would be angle bisector of 75 degree
