Question

draw the following triangles and construct circumcircles for them 1. in triangle abc,ab=6cm,bc=7cm and .angle a=60degree

Answer 1

steps of construction:
●draw the triangle according to the conditions
●draw the perpendicular bicest of each side.
●join them to their opposite angles.
●you will get the common point of intersection.
●it will be the center of your circle.
●with the center draw the circle whose radius is equal to the distance of center to the perpendicular bicest of any of the sides.

the construction is complete.

Answer 2

by using a ruler and compass only, construct triangle ABC,in which BC=6.5cm,AB=5.5cm,AC=5cm. construct the incircle of the triangle and record the radius of the incircle
