Midpoint formula

Distance formula

slope formula

How to find a missing coordinate in a parallelogram?

Find midpoint of the existing diagonal, then find the endpoint using the midpoint to get the missing coordinate.

How to write the equations of the lines of both diagonals in y=mx+b?

Find slope, plug into y=mx+b to solve for b, then rewrite the equation. Repeat this for second diagonal.
