My brother is taking the normal GRE (not the math subject test), and I need to help him learn geometry. I know basic geometry myself, but I need a book that will present it well and will have good exercises. Any suggestions are appreciated.
It seems to me the GRE covers about 50% of U.S. highschool geometry.
Topics in the GRE include:
- Vertical angles
- Parallel lines with a transverse
- Area of "slices" of circles
- Exterior angles of triangles
- Similar Triangles
- Triangles inscribed in circles
