What’s so funny about a trapezoid? Plus, what is a trapezoid? Cartoonist Larry Gonick unlocks the formula to understanding geometry in the latest entry in his bestselling Cartoon Guide series. Moving from the most basic precepts of geometry-planes, lines, and points-to elaborate proofs, The Cartoon Guide to Geometry is a comprehensive primer on all the essential ideas of the subject: angles, triangles, area, similarity, and yes, the Pythagorean theorem. As with Gonick’s other books, the material is carefully tailored to the curriculum standards and standardized testing guidelines of the subject, ensuring that students emerge from The Cartoon Guide to Geometry with a deep grasp of the key ideas.
