The goal of this post is to give you several methods for finding the area of a triangle and a video that goes with each method. The method used to find the area is based on the information you are given.
If you know the Base and Altitude use half base times height
If you don’t know the altitude use Heron’s formula
If you know Two sides and included angle use Side Angle Side ( SAS)
If you know X and Y vertices of the corners use Box Method
If you know Triangle is equilateral use Equilateral Triangle Area
If you know Triangle is isosceles use ½ base times height
Video Half base * height
