"A fascinating look at the geometrical. While this may not be a 'read on the beach' novel, it would prove to be an indispensible classroom companion for those wading into the fascinating subject for the first time."

"A joyously nerdy celebration of the history of geometry and trigonometry, exploring the dozens and dozens of curiosities sitting just beneath the surface of a seemingly ordinary triangle…. By no means a casual read, The Secrets of Triangles is nonetheless worth a look, if only to blow your mind."

"Any science or math holding, especially those catering to lay readers, will find this a winner!"
- Midwest Book Review
