attributes of three-dimensional figures - characteristics that define a geometric figure: edges, vertices, faces (bases), attributes of two-dimensional figures - characteristics that define a geometric figure: sides, vertices, base of a cone - the flat surface shaped like a circle, bases of a cylinder - the two congruent, opposite flat surfaces shaped like circles, congruent figures - figures that are the same size and same shape, decompose figures - to break a geometric figure into two or more smaller geometric figures, edge - where the sides of two faces meet on a three-dimensional figure, face of a prism - a polygon that forms a surface of a prism, polygon - a closed figure with at least 3 sides, quadrilateral - a polygon with 4 sides and 4 vertices, side - a straight outer boundary between two vertices (line segment) of a 2-dimensional figure, sort - grouping objects or figures by a shared characteristic or attribute, three-dimensional figure - a figure that has measurements including length, width, and height, two-dimensional figure - a figure with two basic units of measure, usually length and width, vertex - the point (corner) where three or more edges of a 3-D figure meet; or where two sides of a 2-d figure meet, cone - solid that has one circular base and a point, cylinder - solid that has two circular bases connected by a curved surface, rectangular prism - solid that has 6 faces, 12 edges and 8 vertices. Faces are rectangles., triangular prism - solid that has 5 faces, 9 edges, and 6 vertices, sphere - a non-polyhedran solid that has one curved surface, cube - has 6 faces that are all squares, polyhedran - solid that has faces that are polygons, non- polyhedran - solid that has faces that are not polygons or are curved surfaces,
