ABC is a triangle. Circles with radii as shown are drawn inside the triangle each touching two sides and the incircle. Find the radius of the incircle of the `DeltaABC`.

The ratio of the area of the incircle to the area of Delta ABC is

If the sides of the triangle are 13,14,15 then the radius of the incircle is

The sides of a triangle are 7 cm, 15 cm and 18 cm respectively. What is the radius of the incircle of the triangle?

Ratio of area of the incircle to the area of triangle ABC

In triangle ABC, angleBAC = 90^@, AB = 6 cm and BC = 10 cm. A circle is drawn inside the triangle which touches all the sides of the triangle (i.e., an incircle of DeltaABC is drawn).Find the area of the triangle excluding the circle.

Radius of incircle and circumradius of a triangle

In triangle ABC,a:b:c=4:5:6. The ratio of the radius of the circumcircle to that of the incircle is

One of the side of a triangle is divided into line segmentof lengths 6cm and 8cm by the point of tangency of the incircle of the triangle.If the radius of the incircle of the triangle.If length (in cm) of the longer of the two remaining sides of the triangle is:

A circumcircle is a circle which passes through all vertices of a triangle and an incircle is a circle which is inscribed in a triangle touching all sides of a triangle. Let ABC be a right-angled triangle whose radius of the circumcircle is 5 and its one side AB = 6. The radius of incircle of triangle ABC is r. Area of Delta ABC is
