Find the area of a right triangle
A rectangular triangle is a triangle in which one angle is right and is equal to 90 degrees. The relationship between the sides and angles of a right-angled triangle is at the heart of trigonometry. The area of such a triangle is calculated by the formula: the product of two legs divided by two.
The side opposite to the right angle is called the hypotenuse.
Sides adjacent to a right angle are called legs.
Rectangular triangles are of two types:
- When the legs are equal, then the triangle is called an isosceles right triangle
- If the lengths of all three sides of a right-angled triangle are natural numbers, then the triangle is called a Pythagorean triangle
