🎯 WALT (We Are Learning To)

We are learning to identify and describe the symmetry properties of quadrilaterals.

Success Criteria:

✓ I can identify lines of symmetry in quadrilaterals
✓ I can draw lines of symmetry on shapes
✓ I can recognise rotational symmetry in quadrilaterals
✓ I can describe the symmetry properties of different quadrilaterals

📚 Part 1: Identifying Lines of Symmetry

1. A line of symmetry divides a shape into two identical halves. How many lines of symmetry does a square have?

2 lines

4 lines

6 lines

8 lines

2. Which quadrilateral has exactly 2 lines of symmetry?

Square

Rectangle

Rhombus

Trapezium

3. Which of these quadrilaterals can have NO lines of symmetry? (Tick all that apply)

Irregular quadrilateral

Square

Scalene trapezium

Rectangle

4. Draw the lines of symmetry on each quadrilateral below:

Hint: Use a ruler to draw straight lines. Remember to check if both halves match exactly when folded.

🔄 Part 2: Rotational Symmetry Investigation

5. Rotational symmetry means a shape looks the same when rotated. A square has rotational symmetry of order _______ because it looks identical after turning _______ degrees.

Fill in the blanks: Order _______ , Degrees _______

6. Match each quadrilateral to its rotational symmetry order:

Square

Rectangle

Rhombus

Regular trapezium

Order 4

Order 2

Order 1

7. Explain in your own words what makes a shape have rotational symmetry:

8. Look at the quadrilateral properties below. Complete the symmetry table:

Table to complete:
Square: _____ lines of symmetry, rotational order _____
Rectangle: _____ lines of symmetry, rotational order _____
Rhombus: _____ lines of symmetry, rotational order _____
Irregular quadrilateral: _____ lines of symmetry, rotational order _____
