# Let us draw the following triangles and by drawing incircle of each circle, let us write by measuring the length of inradius in each case.

the lengths of three sides are 7 cm., 6 cm., and 5.5 cm.

Answer :

Steps of Construction:

1. Construct triangle of given dimensions.

2. Name it as ΔABC.

3. Draw angle bisector of ∠A.

4. Draw angle bisector of ∠B.

5. They intersect at O.

6. Draw perpendicular on AB through O.

7. The perpendicular intersects with AB at P.

8. With O as center and OP as radius, draw a circle.

The inradius of the triangle, OP = 1.9cm.
