This Grade 4 worksheet challenges students to count lines of symmetry across quadrilateral types. Through nine fill-in items and a matching activity, learners discover that a square has four lines, a rectangle and rhombus each have two, an isosceles trapezoid has one, and a scalene parallelogram has zero. Tasks build precise Grade 4 vocabulary about symmetry, vertices, and quadrilateral attributes through hands-on reasoning.

Classifying Quadrilaterals
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A Grade 4 square has 4 lines of symmetry.
2. A non-square rectangle has 2 lines of symmetry.
3. A non-square rhombus has 2 lines of symmetry.
4. An isosceles trapezoid has 1 line of symmetry.
5. A scalene parallelogram has 0 lines of symmetry.
6. A general (scalene) trapezoid has 0 lines of symmetry.
7. A kite (not a rhombus) has 1 line of symmetry.
8. Every quadrilateral has exactly 4 vertices, no matter the symmetry count.
9. Among square, rectangle, rhombus, the shape with the most lines of symmetry is the square.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Square (Grade 4)
→ 4 lines of symmetry
1 line of symmetry
Non-square rectangle
→ 2 lines of symmetry
2 lines of symmetry
Non-square rhombus
→ 2 lines along the diagonals
2 lines along the diagonals
Isosceles trapezoid
→ 1 line of symmetry
4 lines of symmetry
