**Problems 11-14**

See the box labeled “Classifications of Quadrilaterals.”

**Problems 15-16**

Remember that complementary angles have measures that add up to 90 degrees, and supplementary angles have measures that add up to 180 degrees.

**Problems 17-20**

Remember that complementary angles have measures that add up to 90 degrees, and supplementary angles have measures that add up to 180 degrees.

**Problems 21-24**

Use Example 2 for the correct classifications.

**Problems 25-32**

Use Example 1 to help you find the correct angles, and then use Example 3 to show you how to classify the angle.

**Problems 33-34**

Use Example 2 for the correct classifications.

**Problems 35-39**

See the box labeled “Classifications of Quadrilaterals.” Draw the named quadrilateral for each problem, and then use your model to answer the questions.

**Problems 40-45**

See Figure 7.18. You will need a compass and a protractor for these problems.

**Problems 46-51**

See Example 6.

**Problems 52-57**
