2. What is this Solid?

3. Rectangular Prism

4. What is this Solid?

5. Triangular Pyramid

6. What is this Solid?

7. Cylinder

8. What is this solid?

9. Cone

10. Solids are three- dimensional objects/shapes (height, length and width) that enclose a part of space

11. Prisms, Pyramids, Cones, Cylinders, and Spheres, are all Solids

12. A Polyhedron is a three dimensional figure whose faces are polygons. Prisms and pyramids are polyhedrons

13. Prism is a solid formed by polygons which are connected at the edges ; they have two congruent bases that are on parallel planes; they are named by the shapes of the polygons which make up their bases

14. Pyramid is a solid formed by polygons connected at the edges; the base can be any polygon and the remainder of the faces are triangles; they are named by the shape of their base

15. Cylinder is a solid with two circular bases that are on parallel planes

16. Cone is a solid with one circular base

17. Sphere is a solid formed by points in space that are the same distance (equi- distant) from a point in the center (a ball)

18. Base is a plane figure. If the solid is a cylinder or prism, there are two bases which are shapes that are parallel and congruent

19. Face is a polygon which makes up the surface of the three dimensional solid.

20. Edge is the line segments where the polygons meet.

21. Vertex is the point where three faces meet; the point where three edges meet

22. Skew lines are lines that do not intersect and are not parallel
