CPM Geometry – Chapter 2

Angles and Measurement
 In this chapter, students will focus on measurement of shapes by examining different types of units (measuring angles, lengths, and areas) and by using tools to approximate the measure of an object. The themes are angles and measurement.  During this chapter:

  • Students will develop algorithms to find exact areas of triangles, parallelograms, and trapezoids when given measurements of base and height.
  • Students will deepen their understanding of angle relationships.
  • Students will also use the Pythagorean Theorem to find perimeter of a triangle.
