How To Find The Perimeter Of A Right Triangle?

Let's look at the geometric characteristics of a right triangle. But first, please review the definition of Perimeter Of Two-Dimensional Shapes, Definitions Of Exponents, and Definitions Of Square Roots, Angle, and Right Angle.

• A right triangle has two unique features.
• The first unique feature of a right triangle, it has one interior angle of exactly 90°. In the example below, this is angle ∠AB. Also note that the sum of the interior angles is 180°.
• The second unique feature of a right triangle is the length of the triangle opposite ∠AB is computed from the lengths of sides A and side B. In the example below, the length of side C is the square root of A² plus B² plus the length of side A and side B.
• Special note, all side of an right triangle must be greater than zero.

Perimeter Of A Right Triangle Formula
Formula = Side A + Side B + Square-Root(Side A² + Side B²) =
Formula = A + B + Square-Root(A² + B²) =
Formula = A + B + √(A² + B²)

AN ALTERNATIVE FORMULA TO COMPUTE THE PERIMETER:
Formula = Side A + Side B + Side C =
Formula = A + B + C
