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.
