A Right Triangle is a triangle in which one angle is right angle (90$^o$) and and the other two remaining angles are equal.

In the above triangle, side "a" is the perpendicular side, side "c" is hypotenuse and side "b" is the base.

## Right Triangle Formulas

Finding Perimeter of the Right Triangle:
By given length of a and b, find the perimeter of a right triangle. We use Pythogorean theorem to find the unknown side c. Substitute a and b in the below formula and find hypotenuse c.

$a^{2} + b^{2} = c^{2}$
The perimeter of the right triangle is given by:

Perimeter = $a+ b+c$

Finding Area of the Right Triangle:
Area of right triangle is half of the base times height.

Area = $\frac{1}{2}$$\times base \times height Area = \frac{1}{2}$$\times b \times a$Substitute a and b and the area of right triangle is calculated.
