Put in the Base value of the triangle first, then put in the height. If you want to do the formula your self, then: Triangle (2D) A = BH/2 Triangular Prism (3D) A = BHL/2 Basically take all of the values, the length, the base, and the height, and then multiply them all together. After that just divide that number that you got by 2. Simple as that! This project is just for you to do this process much faster and easier.
All of the code and art was by me. I came up with the idea once I woke up in the morning. This was definitely hard to make, so if you want a different one were it does trapezoids or parallelograms instead, then go ahead and comment! I can even make a project were I explain how all of this works if you want! I hope you enjoy the project :D
