This book is unique in that it looks at geometry from 4 different viewpoints - Euclid-style axioms, linear algebra, projective geometry, and groups and their in

A fascinating collection of geometric proofs and properties.

By focusing attention on the links between patterns of numbers and shapes, and on connections between algebraic relations and geometric and combinatorial config
