C?

Answer 10

why that?

Answer 11

Cause you need a pencil and a ruler and compass???

Answer 12

but how can you really use the tick marks on the ruler?

The answer to the question is "no" (at least not perfectly).

Answer 13

So instead of using a ruler, you use a straightedge. Both are straight, but the straightedge has no markings on it. It's only used to draw straight lines.

Answer 14

It's a bit counter-intuitive I know. Usually you use a ruler to measure things (like a scale drawing), but in Euclidean geometry, you are usually only allowed a compass, straight-edge, and pencil. This is because the concept of measuring with a ruler isn't accurate.
