Think about the different three-dimensional vocabulary you learned in this lesson.
Name two sets of geometric figures that can intersect to form a point.
Two lines
Three planesIs the face of a cube an example of a point, a plane (flat surface), or skew lines? Explain why it cannot be either of the other two.
Point: a singular location in space.
Plane: a flat surface.
Skew lines: lines in space that do not interesect and are not parallel.The face of a cube has surface area.
