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)
