📐 Part 1: Understanding Angles

1. What is an angle?

A straight line

The space between two rays that meet at a point

A curved line

A circle

2. The point where two rays meet to form an angle is called the:

Centre

Vertex

Edge

Corner

3. A right angle measures exactly:

45°

90°

180°

360°

4. Which of these angles are less than 90°? (Tick all that apply)

Acute angles

Right angles

Obtuse angles

Straight angles

📏 Part 2: Measuring and Classifying Angles

5. Look at the angles below and write the measurement you would expect to see:

a) The corner of a book: _______ degrees

b) A straight line: _______ degrees

c) A complete turn (full circle): _______ degrees

6. Classify these angle measurements. Write acute, right, obtuse, or straight:

a) 45° = _____________

b) 90° = _____________

c) 135° = _____________

d) 180° = _____________

e) 30° = _____________
