How to find the area of a triangle
The area of a polygon is that the amount of square units within that polygon. Area is 2-dimensional just like a rug or an area rug. A triangle is a three-sided polygon. We will look at how to find the area of a triangle?
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted .
The most common way to find the area of a triangle is to take half of the base times the height. Numerous other formulas exist, however, for finding the area of a triangle, depending on what information you know. Using information about the sides and angles of a triangle, it is possible to calculate the area without knowing the height.
To locate the area of a triangle, then multiply the base by the height, then divide by two. The division by two comes in the fact that a parallelogram can be broken into two triangles. By way of instance, from the diagram, the area of each triangle is equivalent to half the area of the parallelogram.
The Formula
Since the area of a parallelogram is A = B * H, the area of a triangle must be one-half the area of a parallelogram. Thus, the formula for the area of a triangle is:
or 
At which b will be the base of the triangle. H is the height of the triangle. And · means multiply.
Given the base and the height of a triangle, we can find the area. Given the area and either the base or the height of a triangle, we can find the other dimension.
Also you can find the area of a triangle using trigonometry, Heron’s formula, vectors, coordinates, line integrals, Pick’s theorem and Formulas resembling Heron’s formula.
