A.ab
b.cd
c.bf
d.fe

Answer 2

a tangent line is a line that touches the circle at one place (even if you extend the line in both directions)

Answer 3

a tangent line will form a right angle with radius of the circle. It looks like you have a few possibilities that *might* be tangents.

We could use pythagoras to show that the triangle formed by the tangent, the radius and the 3rd side is a *right* triangle. Then we know the angle is a 90º, which means the line is a tangent line.

Answer 4

For example, if we look at the line cd, it might be a tangent line.
