A Road for Every Wheel

Students analyze a photograph to solve mathematical questions related to the images captured in the photograph. This month, the mathematics involved in a tricycle with square wheels is explored. Arc length, special right triangles, right-triangle trigonometry, and the law of cosines are all involved...
