Can anyone supply bibliographical details about this book? My geometry book in the 1980s was discontinued and they let students in my class keep their books, but it was lost during a move. Cover said only "GEOMETRY new edition" with no author or publisher. Cover is an orange gradient from a burnt orange around the edges to a hotter orange in the center. Solid triangles with warm colors are arranged in a pinwheel-like design in warm colors (oranges, reds, etc). (I have a scan of this cover done before the loss I'd be happy to e-mail.) Interior text was black, white, and a reddish accent color (not full-color). I used the book in 86-7. If you can help, thanks!
