What will be inradius of a right angle triangle whose base is 13 cm & height is 84 cm ?

In a right angle triangle, the product of two sides is half of the square of the third side (i.e., hypotenuse). Accordingly find out the acute angle?

An angle is equal to 3/7 of its supplement. The angle is :

∆ABC and ∆DEF are similar and their areas are respectively 16 cm² and 64 cm ² . If EF = 6 cm BC is?

Angles of a triangle are in the ratio 3 : 5 : 10. Find the sum of the smallest and middle angle of the triangle.

If G is the centroid and AD, BE, CF are three medians of ∆BDG with area 6cm ² , then the area of ∆ABC is?

If I is the incentre of ΔABC , if  ∠ BAC = 45⁰ , then what is the measure of  ∠ BIC?
