Question

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 triangle is an isosceles triangle having the 7.8 cm. length of base and the length of each equal side of 6.5 cm.

Incircle – It is the circle inscribing the triangle and the point of intersection of angular bisectors of angles of triangle.

Steps in drawing the triangle:

● Draw a line segment of length 7.8cm and name it AB.

● Now take length of 6.5cm in protractor and make an arc from point A, and similarly from point B. Name the point of intersection as C.

Steps for incircle:

● For incentre make an arc from A on side AC and AB, From those arcs make two more arcs, and mark the point of intersection.

● Do the same from point B, and join both the points with vertices.

● Intersection of both the lines will give incentre.

● Distance from any side to incentre will be inradius.

● Inradius=2cm
