All it takes. . .
. . . are a few basic shapes. . .
. . . and a few classic tools. . .
. . . to open up. . .
. . . a world of possibilities.
How do you draw a heptagon? What about a heptakaidecagon? How do you fit circles perfectly into triangles or perfectly around them. . . without a computer? These are the questions this lovely book answers with two simple time honored tools used for centuries by great architects, masons, and craftsmen: the ruler and the compass.
Beautiful and compact, this lovely guide to practical geometric constructions dissects even the most complex shapes into a series of simple lines and circles. Each section gives a succinct overview of the topic followed by a series of examples you can try for yourself. Such a great way to introduce your kiddos to geometry and these classic tools through the shapes themselves rather than complex equations. Bonus? Many of the forms would make beautiful artwork for a child's bedroom!
