QUESTION 7

  1. Consider the image.

    Are ∠EFDand ∠EFCsupplementary?

    Line AB and CD intersect at point F. Ray FE is perpendicular to line AB at point F. Point E lies on the interior of angle AFD. Ray FG is inside the angle CFB where angles CFG and BFG are acute but not congruent. 

    No, because the sum of the two angles is not 90°.

    Yes, because the two angles share a vertex and a side.

    No, because they share a vertex and a side.
