Haven't been on for a long time so thought I would make a quick project! :) Drag points to redraw triangle. Press 'Space' to remove/add grid lines. 'F' to remove/add triangle fill. Numbers rounded to the nearest tenth to avoid repeating decimals and such.
Everything on my own, there were two ways to approach this and I used the Heron's Formula approach which in my opinion was a bit easier. Alternatively, you could make a giant rectangle, subtract triangles and other rectangles as necessary. Please report any bugs! Big thanks to @sfjasmined for curating this! :)
