Triangle Area Calculator
Calculate triangle area using multiple methods: base/height, three sides, or coordinates
About this calculator
The Triangle Area Calculator is a versatile tool that computes triangle area using three different methods to suit various scenarios. Whether you have the base and height measurements, know all three side lengths, or only have coordinate points, this calculator provides accurate results instantly. It's perfect for students, engineers, architects, and anyone working with geometric calculations who needs flexible input options and reliable area computations.
How to use
Select your preferred calculation method from the available options. For base/height method, enter the base length and height values. For three sides method, input all three side lengths. For coordinates method, enter the x and y coordinates of all three vertices. Click calculate to get your triangle area result.
Frequently asked questions
Which method should I use to calculate triangle area?
Use base/height if you know these measurements, three sides for Heron's formula when all sides are known, or coordinates when working with plotted points.
What units does the triangle area calculator use?
The calculator works with any consistent unit system. Enter measurements in your preferred units, and the area result will be in those units squared.
Can I calculate area for any type of triangle?
Yes, this calculator works for all triangle types including equilateral, isosceles, scalene, right, acute, and obtuse triangles using any available method.
