How To Find The Area Of A Right Triangle
Let's look at the geometric characteristics of a right triangle. But first, please review the definition of Area Of Two-Dimensional Shapes, Angle, and Right Angle.
- A right triangle has three unique features.
- The first unique feature of a right triangle
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 is the area of a right triangle
is computed using the length of side A and side B.
Side C is not needed in the area computation.
- Special note, all side of an right triangle must be greater than zero.
Area Of A Right Triangle Formula
Formula = ½ × A × B =
