Question

Draw a triangle ABC in which A=120degree and AB=AC=3Cm. Draw the bisector of angle A.

Answer 1

Draw a base line of 3 cm and name it as A B then from point A ,cut an arc of any convenient measurement ,then from the point where arc has intersected line AB or base line , from that point again cut an arc without disturbing the rounder then again from point of intersection with 1st arc ,cut an arc without disturbing rounder , at the point of intersection ,join that intersecting point of first arc and last arc to point A ,name that point as o then cut an arc of 3 cm from point A on line AO ,name that point of intersection as C and join C from A . You will get your required triangle

To draw angle bisector...join the point of intersection of 2nd arc and 1st arc to point A
