Jonathan was instructed to make a horizon line, place two points on the line and place a third point above the line. I had Johnathan create a vertical line that started from the third point and intersected the horizon line. He placed two additional points on the new line and he attached them to the points on the horizon line. He drew two additional lines that started from the third point and placed them to the left and right of the vertical line. Jonathan used the intersections to create a cube. He placed a forth point above the third point and connected it to the four corners of the top of the cube.
