1.7 Three-Dimensional Figures Polyhedron A solid with all flat surfaces that enclose a single – region of space. Face The polygons that make up the flat surface. – Edge The line segments where the faces intersect. – Vertices The point where three or more edges intersect. – Regular Polyhedron A polyhedron with all faces being regular – congruent polygons. Surface Area A two-dimensional measurement of the surface of a – solid figure. Volume The measure of the amount of space enclosed by a solid – figure.
