Question

draw a triangle with sides 6cm , 7 cm and 9cm and draw its urcum circle
​

Answer 1

Step-by-step explanation:

Steps of Construction:-

1.) Construct △ABC having sides BC=7cm,AC=5cm and AB=6cm.

2.) Draw angle bisector of any two angles say ∠B and ∠C of △ABC and let these intersect at a point say O.

3.) Draw perpendicular from O on any side of triangle, say OP on BC.

4.) Taking O as centre and OP as radius, draw a circle.

5.) The circle touches the other two sides of triangle. This will be the required in circle of the triangle.

Radius, OP of incircle is 1.6 cm.
