CHAPTER 11: 2-D AND 3-D GEOMETRY
Lesson 1: Veritcal and Horizontal Lines and Faces
Goal
Identify how to draw horizontal and vertical lines, edges and faces.
Instructions for Use
Click on either “Prisms” or “Pyramids” and then click on a shape you wish you see. Determine how many edges, vertices, and faces there are. Place the shape in one position: How many edges are horizontal in this position? How many are vertical? How many faces are horizontal? How many are vertical?
Manipulate and color each shape to explore the number of faces, edges, and vertices. Click “New Shape” to get another shape. For each shape determine which faces and which edges are vertical and which are horizontal.
