- Draw a line that passes through A and B.
- Draw a line that is perpendicular to line segment AB. This will create a point C.
- Draw a square with vertices D(5, 0), E(5, 5), F(0, 5), and G(0, 0).
- Change the color and the opacity of the square. The opacity is the extent to which the shape is see-through.
