7-2A Similar Triangles
... SKYSCRAPERS Josh wanted to measure the height of the Sears Tower in Chicago. He used a 12-foot light pole and measured its shadow at 1 p.m. The length of the shadow was 2 feet. Then he measured the length of Sears Tower’s shadow and it was 242 feet at the same time. What is the height of the Sears ...

3-3 Parallel and Perpendicular Lines
... Suppose that the top and bottom pieces of a picture frame are cut to make 60° angles with the exterior sides of the frame. At what angle should the two sides be cut to ensure that opposite sides of the frame will be parallel? In order for the opposite sides of the frame to be parallel, same-side int ...
