Define a straight line perpendicular to a plane, and prove that when a straight line is perpendicular to two straight lines drawn through its foot in a plane, it is perpendicular to the plane. 2. Prove that, if two solids have equal bases and heights, and if their sections, made by any plane parallel to the common plane of their bases, are equal, they are equivalent.
