Ch 38: WEST Math: Quadrilaterals

About This Chapter

The Washington Educator Skills Test (WEST) is now the National Evaluation Series examination. Review this chapter's topics on the characteristics of quadrilaterals as you prepare to add an endorsement to your Washington teaching certificate.

WEST Math: Quadrilaterals - Chapter Summary

Review the features of various kinds of quadrilaterals through the animated video lessons in this chapter. The lessons will allow you to explore the properties of rectangles, squares, parallelograms and trapezoids. Use this chapter as a study tool as you prepare to take the WEST Math examination. The topics in the lessons will help you to:

  • Define a parallelogram and identify its sides and angles
  • Calculate the area of a parallelogram and a rhombus
  • Find the area and perimeter of a square, the sides and angles of a rectangle, and the area of a trapezoid
  • Review the area of complex shapes

These video lessons can be used as a study resource while you prepare to pass the WEST Math examination. The material in the video lessons is presented by experienced educators who will answer your questions on quadrilaterals. Study at your own pace and review the lessons with the video tags. You may also refer to the corresponding written transcripts. Then, test your retention of quadrilaterals concepts by taking the self-assessment quizzes.

WEST Math: Quadrilaterals - Chapter Objectives

You will answer questions on quadrilaterals in the Measurement and Geometry section of the computer-based WEST Math examination. This third section of the five-part test will make up 19% of your overall score. The examination will ensure that you understand measurement principles and procedures as well as the applications of perimeter, circumference, volume and area when solving problems. Successfully answering 150 multiple-choice examination questions could result in the addition of a mathematics endorsement to your Washington teaching certificate.
