Re: Area of traingle with tree side
All triangles have three sides.
There are two main formulas that do not call on trigonometric ratios.
The classic one:
- 1. You need the length of a base and it corresponding height (the length of the segment perpendicular to that base and passing through the vertex (summit) opposite to that base. Area=(1/2) * (measure of the base)*(measure of the height). The base and height must be expressed in the same unit.
Heron's Formula if you have the length of the three sides. Let those measures be a, b, and c.
- Calculate the semi-perimeter p with p=(1/2)(a+b+c)
- Area=Square root of (p*(p-a)*(p-b)*(p-c))
- a, b, and c must be expressed in the same unit.
