Chp. 10 Lesson 5 –Solid Figures

3. Parts of three dimensional figures
face – the polygons that form the solid figure. edge – the segments where the faces of a figure meet. vertex – the point where edges meet. (The plural is vertices.) edges face vertex

4. Counting faces, edges & vertices ex.
Ex. Count the number of faces, edges, and vertices of the square pyramid shown. faces: 5 edges: 8 vertices:

5. Classifying solids
prism – a solid with two parallel bases that are congruent polygons. Ex. rectangular prism and triangular prism cylinder – a solid with two parallel bases that are congruent circles. Ex. pyramid – a solid made with polygons. The base can be any polygon, and the other polygons are triangles that share a common vertex.

6. Classifying solids Continued
cone – a solid with one circular base and a vertex that is not in the same plane. Ex. sphere – the set of all points that are the same distance from a pointed called the center.

7. How to draw a solid
Draw a triangular prism. (textbook pg. 542) (1) Draw the congruent bases (2) Connect the corresponding vertices. (3) Make hidden lines by partially erasing lines.
