1 maps to 1

2 maps to 3

3 maps to 2

Step-by-step explanation:

the correctly assigned answer options describe everything.

there is not much else to say and explain.

these are all true statements due to the symmetry principle of a circle.

and yes, the perpendicular radius (or diameter) of the circle towards such a line cuts this line in half.
