Thank you so much.

]]>Here is a two point perspective PERFECT square.

To do this you need to find the third vanishing point (this is between the two others). So to find it you need to connect two lines from the right and the left vanishing points and then to find the 90 degrees angle of the connected lines, I draw square with a 45 degrees line which connects the two corners of the square

here the example

So what I do is, to rotate this square and scale up until it touch/sit/crossover with both vanishing points (Left and Right) and touch to the angle which I want to create the perfect square like this image

And the middle line intersect with the horizontal line is the spot of the third vanishing point.

I hope that you understand how I work and what i want to tell you, it's really complicated so I hope that there is a solution.

Thank you very much.

The angles in your square are 90, 70, 145, 55. That adds up to 360 degrees.

The angles of the red dot corners are 35, 90, 55. That equals 180. And the angles of the blue dot corners are 20, 70, and 90. Also equals 180. The math all works out.
