    See the box labeled "Classifications of Quadrilaterals."

    See the box labeled "Classifications of Quadrilaterals." Draw the named quadrilateral for each problem, and then use your model to answer the questions.
    Problems 25-30
    See Figure 7.18. You will need a compass and a protractor for these problems.
    Problems 31-35
    Use Example 2 for the correct classifications.
    Problems 36-43
    Use Example 1 to help you find the correct angles, and then use Example 3 to show you how to classify the angle.
    Problems 44-49
    See Example 6.
    Problems 50-55
    See Example 5.
