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**
