## 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.
