Note that distances are equal andtherefore side faces 1 and 2 appear alike. B. Measure middle vertical A B of tracing on strip of with actual length of edge A B in model. A B appearsshorter than its real length because, being below the eye, it isseen obliquely and foreshortened. C. Measure length of C D in tracing and compare with A
