Triangle Area Calculator

A Triangle Area Calculator is a tool used to determine the area of a triangle based on given inputs such as base and height, three sides, or coordinates of vertices.

Why use a Triangle Area Calculator?

Manually calculating the area of a triangle can be tedious, especially for irregular triangles. A calculator simplifies the process, reducing human error and saving time. It is commonly used in geometry, engineering, architecture, and real-world applications like land measurement.

How does a Triangle Area Calculator work?

The calculator typically uses one of these formulas depending on the available inputs:

1. Base & Height Formula:

   Area=1/2×Base×Height
   • Used when base and height are known.

2. Heron’s Formula (Three Sides Given):

   

   where is the semi-perimeter of the triangle.

3. Coordinate Formula (Vertices Given):

   
   • Used when the coordinates (x1,y1), (x2,y2), and (x3,y3) are known.

When is a Triangle Area Calculator Used?

• School & College: For solving geometry problems.
• Construction & Engineering: Estimating land areas or material usage.
• Cartography & GIS: Calculating areas on maps.
• Programming & Computer Graphics: Collision detection and mesh calculations.
