PERSPECTIVES & SOL QUESTIONS
SOL Tests frequently have several questions which involve how a geometric shape looks when viewed from certain given perspectives. I have seen some which use pipes and the question asked is which objects are parallel. Their are many variations to this type of question. GollyGee Blocks is a great teaching tool for this type of question since the program allows the user to rotate the building plane in the horizontal and vertical. Wire frame mode also helps in "seeing" the object as the observer would.
In this simple example I have a girl looking at a pyramid stacked on a cube. The girl is at a corner of the stacked object. What would her view look like?
If I rotate the plane so that I am behind the girl, this is what she would see.
Try this exercise by building an isometric of stacked cubes. Take a look from all angles. Have fun.
