Whats a line in geometry

This app works really well,but it doesn't always show you the answer. This app is great you could have your math homework done in 1 hours or less, it helps me with my math and I really needed to help because no other apps would let me use fractions but this one did and I'm grateful for that because now I got a in math.

I wish you could view steps without paying, but at least you can watch a video to view them. Gives me all the answers I need and explains each step very clearly. It has detailed explanations and clear and understandable formulas.

This app really helps me with math problems nothing wrong with it it has adds but they don't bother and I definitely recommend using this app for mostly any math problem, especially for those freaking huge problems that take forever to type, amazing app, got my F to an A with flying colors. An excellent scholastic aide, though one should not become overly-reliant on such devices.
