This is a geometric triumph of mine, where I have managed to get the equations for inscribing a circle in an angle with many variables. To use the project, there are about 3 things you can do. You can drag the angled green line to change the angle measure. You can also drag the red dot/horizontal line to change the center point of the angle. To change the distance of the circle from the center, drag the circle. the circle goes to the x position of the mouse. These formulas here are based on being a function of the inputs of the angle (Dir) and the circle X position (Cx), and having the Y position (Cy), radius (Cr) and distance(Cdist) as outputs. however, they can be algebraically manipulated to have it have whatever you want as an input or output. I made this, just like the pen size experiment, as part of the final goal of having a way to fill triangles faster.
