This book uses a holistic view of geometry to introduce axiomatic, algebraic, analytic, and differential geometry. Starting with an informal introduction to nonEuclidean plane geometries, the book develops the theory of these geometries to put them on a rigorous footing. It can be considered an explanation of the Kleinian view a la Erlangen Programme. The treatment, however, goes beyond the Kleinian view of geometry. Some noteworthy topics presented include ...  various results about triangles (including results on areas of geodesic triangles) in Euclidean, hyperbolic, and spherical planes
 affine and projective classification of conics
 twopoint homogeneity of the three planes and
 the fact that the set of distance preserving maps (isometries) are essentially the same as the set of lengths preserving maps of these planes.
Geometric intuition is emphasized throughout the book. Figures are included wherever needed. The book has several exercises varying from computational problems to investigative or explorative open questions.
