Triangle Area Calculator
Calculate the exact area of any triangle using its base and height.
The Area of a Triangle
The simplest and most common method to find the area of a two-dimensional triangle is using the base and the height.
The Formula
The mathematical formula is: Area = (Base × Height) / 2.
Think of a triangle as exactly half of a rectangle. If you multiply the base by the height, you get the area of a rectangle. Dividing by two gives the triangle's area.
Frequently Asked Questions
Does it matter which side I use as the base?
No, you can use any of the three sides as the base, as long as the "height" is measured as a perpendicular line drawn from that base to the opposite vertex.
