Dear Everyone,

So I would like some recommendation for high school geometry books that are affordable and preferably e-books.

Why do I need some books on high school geometry? I would like to improve my geometric reasoning. When I took high school geometry a decade and half ago, I was freshman in high school and not paying attention to the subject. I understand that I have a deficient in spatial reasoning as well as having a hard time picturing congruences and similarities between polygons and triangles.

I understand some basics, but I would like to know the intermediate knowledge. When I took high school trigonometry, I enjoyed the subject and understood the topics up to the applications to geometry (where I had trouble with it). So far, the geometry books that I have are Master Math Geometry and 300 level geometry book- Euclidean and non-Euclidean geometry by Greenberg.

Thanks,
cbarker1

The book with the best title is Geometry for Enjoyment and Challenge, by Rhoad, Milauskas and Whipple.
The inside is pretty good too.

There are other ways to improve your spatial reasoning beyond studying Geometry. Can you say more about what situations you find yourself in where you wish you had better 3-D visualization skills?

One way to work on this (sorry for the engineering perspecive) would be to download a free 3-D CAD drawing tool package and experiment with drawing 3-D objects and rotating them. That may help you to start getting a better 3-D perspecive and mental model of things...

The authors of the book I used 50 years ago was Dolciani and Plane. I have no idea how I remember this after 50 years.

Correctiom: it is just Dolciani, Modern Geometry. I got confused
The chemistry text I used in Sienko and Plane. I interposed the Plane as an author in geometry.
