A series of five photographs show the three most familiar geometric forms.

Meet Triangle. He is going to play a sneaky trick on his friend, Square. Or so Triangle thinks. . . . With this first tale in a trilogy, partners in crime Mac Barnett and Jon Klassen will have readers wondering just who they can trust in a richly imagined world of shapes. Visually stunning and full of wry humor, here is a perfectly paced treat that could come only from the minds of two of today’s most irreverent — and talented — picture book creators.

From the dream team of Jon Klassen and Mac Barnett comes the second instalment in the exciting new shape trilogy. Every day, Square brings a block out of his cave and pushes it up a steep hill. This is his work. When Circle floats by, she declares Square a genius, a sculptor! “This is a wonderful statue,” she says. “It looks just like you!” But now Circle wants a sculpture of her own, a circle! Will the genius manage to create one? Even accidentally?

The three most basic shapes -- squares, triangles and circles -- are all around us, from the natural world to the one we've engineered. Full of fascinating facts about these shapes and their 3D counterparts, Shapes in Math, Science and Nature introduces young readers to the basics of geometry and reveals its applications at home, school and everywhere in between. Puzzles and activities add to the fun factor.

The study of the arithmetical properties of triangles dates back to ancient Greece, and possibly beyond. This classic text, written by a distinguished mathematician and teacher, focuses on a fundamental cornerstone of elementary geometry, the theorem of Pythagoras, and its applications.
