## How Do I Find The Area Of Obtuse Triangle?

Let's look at the geometric characteristics of an obtuse triangle. But first, please review the definition of Area Of Two-Dimensional Shapes, Angle, and Obtuse Angle.

- An obtuse triangle has one unique feature,
at least one of the interior angle is greater than 90°, and the sum of the angles
is 180°. In this example
**∠AB**is greater than 90° by visual observation. - Special note, all sides of an obtuse triangle must be greater than zero.

**Area Of An Obtuse Triangle**

Area = ½ × H × B
