This quick lesson is all about how to find the Area of a Triangle using Heron’s Formula.
But, isn’t the area of a triangle just one-half the base times the height?
Oblique Triangle
Yes, but what happens if you don’t have the height?
The beauty of these new area formulas is that while knowing the height of a triangle is ideal, it’s not necessary for finding area because we have trigonometry (i.e., the sine function) at our fingertips.
And these new formulas can be used regardless of the type of triangle we have:
- acute
- obtuse
- right
Additionally, two thousand years ago, Hero (or Heron) of Alexandria, a Greek mathematician, developed a way to calculate the area of a triangle, when the lengths of three sides of a triangle are known, as stated by Math is Fun.
In fact, Heron’s Formula just takes two quick and easy steps!
As you will soon see, these new area formulas are simple to use and can be applied to any triangle that we can encounter…even right triangles!
