Besides sharpening your mind for logical thinking, analytical reasoning, and problem solving, geometry has plenty of real world applications.

Just as it was used by ancient Greek and Roman architects to build their stately temples and civic buildings, modern architects use the same principles to build massive modern skyscrapers.

Who else uses geometry? Artists and sculptors, car builders, video game creators, astronomers, robotics engineers, gardeners, landscapers, and the list goes on.

Around the Web, try your hand at fun and challenging geometry lessons, games, and exercises that will have you figuring out the angles in no time ...
