Grade 7 supplementary angles practice quiz

📚 Topic Summary

Supplementary angles are two angles that add up to 180 degrees. Think of it like this: if you have one angle, the supplementary angle is the amount you need to reach a straight line. Understanding this relationship is key to solving many geometry problems, especially when dealing with triangles and other polygons.

Let's get started! This quiz will help you practice identifying and working with supplementary angles.

🧠 Part A: Vocabulary

Match the term with its definition:

1. 📐 Angle
2. ➕ Supplementary Angles
3. 📏 Degree
4. ↔️ Straight Angle
5. ➗ Complementary Angles

1. A. The unit of measurement for angles.
2. B. Two angles that add up to 90 degrees.
3. C. Two angles that add up to 180 degrees.
4. D. A shape formed by two lines diverging from a common point.
5. E. An angle measuring 180 degrees.

Match each number to a letter above.

✏️ Part B: Fill in the Blanks

Complete the following paragraph using the words provided: 180, angle, supplementary, degrees, straight.

Two angles are considered __________ if their measures add up to __________ __________. A __________ angle measures 180 __________. Therefore, if you know the measure of one __________, you can find its supplement by subtracting it from 180.

🤔 Part C: Critical Thinking

Imagine you're designing a ramp for a skate park. Explain how understanding supplementary angles might be helpful in ensuring the ramp is safe and fun to use. Give a specific example.
