Enter a value for all fields

The **Area of a Triangle Based on the Base and Height** calculator computes the area of a triangle given the length of the base (b) and height (h).

**INSTRUCTIONS:** Choose units and enter the following:

- (
**b**) Length of Base of Triangle - (
**h**) Height of Triangle

The formula for the area of triangle is:

`A = 1/2 * b * h`

where:

- A = area of triangle
- b = length of the base
- h = vertical height

A **triangle** is a polygon with three sides, three vertices (corners), and three angles. **Triangles **can be classified based on the lengths of their sides and the measures of their angles as follows:

By Side Lengths:

**Equilateral Triangle**: All three sides are equal in length.**Isosceles Triangle**: Two sides are equal in length.**Scalene Triangle**: All three sides have different lengths.

By Angle Measures:

**Acute Triangle**: All three angles are less than 90 degrees.**Right Triangle**: One angle is exactly 90 degrees.**Obtuse Triangle**: One angle is greater than 90 degrees.

The sum of the interior angles of any triangle always adds up to 180 degrees.
