Measuring Angles with Protractors

Protractor and angles illustration

📐 Part 1: Angle Types and Measuring

1. Match each angle measurement to its correct type:

35°

Right angle
Acute angle
Obtuse angle
Reflex angle

90°

Right angle
Acute angle
Obtuse angle
Reflex angle

125°

Right angle
Acute angle
Obtuse angle
Reflex angle

280°

Right angle
Acute angle
Obtuse angle
Reflex angle

2. Using your protractor, measure these angles to the nearest degree:

Angle A: _____ degrees Type: ___________

Angle B: _____ degrees Type: ___________

Angle C: _____ degrees Type: ___________

Angle D: _____ degrees Type: ___________

3. Which scale should you read on a protractor when measuring an acute angle?

Always the inner scale (0-180°)

Always the outer scale (0-180°)

The scale that gives the smaller reading

Either scale - they both work

4. Extension: Write the correct angle notation for the angles you measured above:

Angle A: ∠______ = ______°

Angle B: ∠______ = ______°

✏️ Part 2: Drawing Angles

5. Draw the following angles accurately using your protractor. Label each angle clearly:

a) Draw an acute angle of 42°




b) Draw an obtuse angle of 135°




c) Draw a reflex angle of 250°




6. Challenge: Draw two adjacent angles that add up to 90°. Measure and label both angles.

Angle 1: _____ degrees

Angle 2: _____ degrees

Total: _____ degrees




🎯 Part 3: Problem Solving

7. Complete these angle facts:

a) Angles on a straight line add up to ______°

b) Angles around a point add up to ______°

c) A complete turn is ______°

8. If one angle on a straight line measures 115°, what is the size of the other angle?

Working: ________________

Answer: ______°

9. Extension: Three angles meet at a point. Two of them measure 85° and 140°. Calculate the third angle.

Working: ________________

Answer: ______°

10. Self-Assessment: Tick the success criteria you have achieved today:

I can name and describe different types of angles

I can correctly use a protractor to measure angles

I can accurately draw angles of given measurements

I can use correct angle notation in my work
