Unit 8
Geometry

We use geometry every day. Consider the comments you hear on a regular basis: “the puck came off the boards at a bad angle,” or “the trajectory of the bullet indicates that it came from above,” “he covers all the angles.” These and other phrases indicate the importance of geometry in our lives. In this unit, we explore geometrical concepts.

Objectives

After completing this unit, you should be able to

1. discuss characteristics of points, lines, angles and triangles.
2. calculate the perimeter and area of two-dimensional figures, such as triangles, quadrilaterals, polygons and circles.
3. calculate the angles of two-dimensional figures, such as triangles, quadrilaterals and polygons.
4. calculate the volumes and surface areas of three-dimensional figures, such as cubes, cones, spheres, cylinders, pyramids and rectangular prisms.

Note: The course uses Canadian forms of measurement, that is, the metric system. If you feel you need more practice with the metric and other systems of measurement, work through Chapter 6 in the textbook.
