What's Your Angle, Pythagoras?: A Math Adventure

An addition to the Math Adventure series, What's Your Angle, Pythagoras? by Julie Ellis, illus. by Phyllis Hornung, tells a fictional tale of the future Greek philosopher and mathematician. Ellis characterizes Pythagoras as a boy always underfoot, trying to help solve problems for his family and neighbors. A trip to Egypt and a chance encounter with a builder inspire him to think about right angles in new ways and he devises the theory that bears his name today. (July) .
