In a right angle triangle,if `r=2,R=6` then area of the triangle is `(A) 14` `(B) 42` `(C) 28` `(D) 56`

In a right angles triangle, prove that r+2R=s.

In a right angled triangle a^2+b^2+c^2 is :

The hypotenuse of a right-angled isosceles triangle is 5cm. The area of the triangle is (a) 5cm2 (b) 6.25cm2 (c) 6.5cm2 (d) 12.5cm2

The difference between the sides at right angles in a right - angled triangle is 14 cm . The area of the trangle is 120 cm^(2) . Calculate the perimeter of the triangle.

What is the height of the right angle triangle ? I. It is a right-angled triangle. II. The area of the triangle is 5 times its base.

If the perimeter of a right angled isosceles triangle is (6 + 3 sqrt(2)) m, then the area of the triangle will be
