Area of Right Triangle
|
A right triangle is the one in which the measure of any one of the interior angles is 90 degrees. It is to be noted here that since the sum of interior angles in a triangle is 180 degrees, only 1 of the 3 angles can be a right angle. If the other two angles are equal, that is 45 degrees each, the triangle is called an isosceles right angled triangle. However, if the other two angles are unequal, it is a scalene right angled triangle. Area of Right Triangle = Perimeter of a right triangle = a + b + c = Sum of three sides Where a, b and c are the measure of its three sides. Illustration: Find the area of a right triangle whose side forming the right angle are 3 cm and 4 cm. Solution: Let the base = 3 cm and height = 4cm Illustration: Find the area of the right triangle if base and height of the triangle are 5 cm, 7 cm respectively. Solution: As we know that Area of right triangle = So, Area = Area = |
