Geometry seems to be one of those subjects that either clicks automatically for the student or takes a bit more working it out until it clicks. (Math in general, seems to be that way!)
BUT... I have textbook downloads here for you! I also have videos, printable manipulatives, worksheets, online games and more right here for YOU. FREE.

Tips from my house-
Hands on cubes and pyramids you print out and tape together help. You can create your own from graph paper.
Legos, unifix cubes and Math-U-See blocks can bring about visualization of the math problem or math concepts.
Some people might have sugar cubes on hand.
Don't forget that cans are great cylinders and a tangram set can be great resources.
