Hello

I believe that solving geometry problems makes a big challenge for a lot of people in competitive programming and I am one of them

I have been wondering if someone could share a book which is kind of good to master the basics ... (vector algebra , 2d geometry lines and points and stuff , polygons ... etc)

I don't know why searching for a geometry guide was really hard and I couldn't come up with a good book (most of them are really advanced)

Can somebody share the name of a nice book?
