Solid Figures: Solid figures are closed, three dimensional figures. These are shapes that we see daily, such as a rectangular prism (T.V.) and a sphere (balls). Terms to know: Edge: the side of a plane figure. Vertex: the corner of a plane figure, where two edges meet. Vertices: more than one vertex. Base or Face: the flat surface of a solid figure. Congruent: same size and shape. Equal. Parallel: opposite lines, or edges, going in the same direction. The edges, or lines, will never cross. Prism: A prism is a figure made of two parallel faces that are polygons of the same shape and sides that are parallelograms. Spheres: A figure with a curved surface in which all points on the surface are equal distance from the center. Cones: A cone has a circular base connected to a vertex Cylinders: A cylinder has two equal circular bases that are parallel Rectangular Prisms: prisms with rectangular faces. Triangular Prisms: prisms with triangular faces Pyramids: figures with a base that is a polygon and triangular sides. Pyramids can have a rectangular base or a triangular base. Cubes: prisms with squares for sides and faces. Explore the links to learn about different solid figures! |
