I am taking quiz corrections and as you see Iwrote one statement correct about theconstitution but I got the other 2 wrong.Based on that construction what are 2 othercorrect statements?

As we can see in the shown figure:
1) I and J are parallel
2) I and g are perpendicular because we have constructed the steps to make the perpendicular to the line I
3) J and g are perpendiculars because I and J are parallel and I perpendiculars to g
