How to calculate the Area of a Triangle
This is a simple math tutorial aimed at middle school students, explaining how to calculate the area of a triangle (and the reasoning behind the method).
How to calculate the area of a triangle
A triangle is not that much different. As you can see below, two triangles that are of mirror image, can combine to create a four sided shape.
You can see in the above video tutorial how this works with any type of triangle. This means that the area of a triangle is exactly half that of a four-sided shape with the same height and width.
This is demonstrated in the below example.
