Space Figures Go to: http://www.math.com/school/subject3/lessons/S3U4L1GL.html 1. Click on the polyhedron link. Define polyhedron. 2. What are the polygons or flat surfaces of a polyhedron called? What are the intersections of these polygons or flat surfaces called? 3. Click on Next at the bottom of the page to go to Step 2: In Depth. A prism can be generated by moving a polygon (triangle or rectangle) through space. A cylinder can be formed by moving a circle through space. In both cases, depth is being added to a flat surface. Can cones and spheres be generated in the same way? If not, why not and how can they be generated? 4. What space figure has one circle base? 5. What space figure is formed by moving a circle vertically through space? 6. Read Step 3: Examples. According to the first and last questions, square and hexagonal prisms can be formed by moving a square or hexagon horizontally through space. Thisstatement is true only if the square or hexagon is vertical. If the square or hexagon is horizontal, in what direction must it be moved through space to form a prism? How does the movement through space depend on the location of the original flat surface? Cross Sections Go to: https://www.mathsisfun.com/geometry/cross-sections.html 7. What is the cross section of a cube? 8. What is the cross section of a sphere? 9. What is a vertical cross section of a cone? 10. What is the horizontal cross section of this prism?
