Protractor Angle Measurement Guide

Student using protractor to measure angles

📐 Part 1: Protractor Steps & Vocabulary

1. Number the steps for using a protractor correctly (1-4):

Read the scale where the angle line crosses

Place the centre point on the vertex

Line up the baseline with one side of the angle

Choose the correct scale (inner or outer)

2. Match the angle types with their Māori translations:

Angle (tōrino): _______ degrees

Vertex: The _______ point where two lines meet

Degree: Unit of angle _______

3. Circle the correct angle type for each measurement:

45° is: acute / obtuse / right / reflex

90° is: acute / obtuse / right / reflex

135° is: acute / obtuse / right / reflex

270° is: acute / obtuse / right / reflex

🕐 Part 2: Real-World Angle Measurement

4. Use your protractor to measure these clock angles:

3 o'clock angle = _____ degrees (Type: _______)

2 o'clock angle = _____ degrees (Type: _______)

5. Measure and identify angles in your classroom:

Corner of your desk = _____ degrees

Open door angle = _____ degrees

Folded paper corner = _____ degrees

6. Year 5: Identify angle types using benchmarks (90°, 180°, 360°)

45° is less than 90° (acute)

120° is between 90° and 180° (obtuse)

200° is greater than 180° (reflex)

7. Year 6: Draw angles to the nearest degree using your protractor:

Draw a 65° angle

Draw a 110° angle

Draw a 225° reflex angle

🏠 Part 3: Problem Solving with Angles

8. A door opens from 0° to 90°. If it's halfway open, what angle is it at?

Answer: _____ degrees

9. Extension (Advanced): If one angle is 85°, what is its reflex angle?

Calculation: 360° - 85° = _____ degrees

10. Real-world application: Name three objects in your home that show different angle types:
11. Reflection: Explain how you know if you're reading the correct scale on your protractor:

Support Notes:

• ESOL learners: Use vocabulary cards with pictures

• ORS support: Work with a buddy, use larger protractors

• ASD support: Follow step-by-step visual guide

• Dyslexia support: Colour-coded angle types, oral instructions available
