Is line e perpendicular to line g?

• Yes, because line e is perpendicular to line f, and lines f and g are parallel.

• No, because while line e is perpendicular to line f, we don't have enough information to know lines f and g are parallel.

Which of the following statements is true based on the image?

• Segments AD and CF are parallel to Segment BE.

• Segment BC and EF are skew.

• Segments AB and DF are skew.

• Segments DE and FE are parallel.

• Plane DEF and Plane ABC are parallel planes.
