Lines of symmetry worksheet for Grade 4 geometry practice.

Let me carefully examine the image to identify which shapes have lines of symmetry and which do not.

I'll go through each shape one by one:

1. Star (top left): This is a 4-pointed star. It has vertical, horizontal, and two diagonal lines of symmetry. So it has lines of symmetry.

2. Heart (top middle): A standard heart shape has one vertical line of symmetry down the middle. So it has a line of symmetry.

3. Lightning bolt (top right): This shape is irregular and asymmetrical. If you try to fold it in half vertically, horizontally, or diagonally, the sides won't match. So it does NOT have any lines of symmetry.

4. Pentagon-like shape (middle left): This appears to be a house-shaped pentagon (rectangle with triangle roof). It has one vertical line of symmetry down the center. So it has a line of symmetry.

5. Square (middle center): A square has 4 lines of symmetry (vertical, horizontal, and two diagonals). So it has lines of symmetry.

6. Down arrow (middle right): This green arrow has one vertical line of symmetry down the center. So it has a line of symmetry.

7. Rectangle (bottom left): A rectangle has 2 lines of symmetry (vertical and horizontal through the center). So it has lines of symmetry.

8. Curved arrow (bottom middle): This is a U-shaped arrow turning right. It's asymmetrical - if you try to fold it, the ends don't match. So it does NOT have any lines of symmetry.

9. Smiley face (bottom right): A standard smiley face with two eyes and a curved mouth has one vertical line of symmetry down the center. So it has a line of symmetry.

Now I need to identify which shapes do NOT have any lines of symmetry - those should get an "X" through them.

From my analysis:
- Lightning bolt (top right) → no symmetry → needs X
- Curved arrow (bottom middle) → no symmetry → needs X

Let me double-check the curved arrow: It's a brown arrow that curves from bottom left to top right in a U-shape. Yes, this is definitely asymmetrical - there's no way to fold it so both sides match.

The lightning bolt is clearly asymmetrical too.

So the answer should be that we draw an X through the lightning bolt and the curved arrow.

Since the question asks to "draw them" (lines of symmetry) for shapes that have them, or "draw an X through it" for shapes that don't, and we're to provide the final answer, I need to specify which shapes get X marks.

Final Answer: The lightning bolt and the curved arrow should have an X drawn through them.

Wait, let me make sure I'm interpreting the task correctly. The instruction says: "If a shape below has lines of symmetry, draw them. If a shape does not have any lines of symmetry, draw an X through it."

Since this is a text-based response, I should indicate which shapes need X marks.

Looking at the 9 shapes arranged in 3 rows of 3:
- Row 1: star (has symmetry), heart (has symmetry), lightning bolt (no symmetry)
- Row 2: pentagon/house (has symmetry), square (has symmetry), down arrow (has symmetry)
- Row 3: rectangle (has symmetry), curved arrow (no symmetry), smiley face (has symmetry)

So only 2 shapes need X: the lightning bolt (top right) and the curved arrow (bottom middle).

Final Answer: Draw an X through the lightning bolt shape and the curved arrow shape.
