Lines of symmetry #3 | 3rd grade, 4th grade Math Worksheet ... - Free Printable

I need to solve this symmetry worksheet. The task is to complete each drawing using the dotted line as the line of symmetry.

Let me work through each shape systematically:

Top section (3 shapes):
1. First shape: A parallelogram with a diagonal dotted line - need to reflect it
2. Second shape: A T-shape with vertical dotted line - need to complete the right half
3. Third shape: An L-shape with diagonal dotted line - need to reflect it

Grid section (16 shapes in 4x4 grid):

Row 1:
1. Triangle with horizontal base, dotted line through middle horizontally - complete top half
2. Semicircle with vertical dotted line - complete left half
3. Semicircle with horizontal dotted line - complete bottom half
4. Rectangle/triangle with diagonal dotted line - reflect across diagonal

Row 2:
5. Right triangle with diagonal dotted line from corner to corner - reflect
6. Parallelogram with diagonal dotted line - reflect
7. Right triangle with diagonal dotted line - reflect
8. Irregular shape with diagonal dotted line - reflect

Row 3:
9. Triangle with vertical dotted line - complete right half
10. Semicircle with vertical dotted line - complete right half
11. L-shape with vertical dotted line - complete right half
12. Irregular quadrilateral with diagonal dotted line - reflect

Row 4:
13. Stepped shape with diagonal dotted line - reflect
14. L-shape with diagonal dotted line - reflect
15. Curved shape with diagonal dotted line - reflect
16. Complex shape with diagonal dotted line - reflect

For each shape, I need to mirror what's on one side of the dotted line to the other side. The dotted line acts like a mirror - whatever is drawn on one side should be reflected exactly on the other side.

Since I cannot actually draw the completed shapes here, I'll describe what needs to be done for each:

Final Answer:

To complete each drawing:
- For shapes with vertical dotted lines: Mirror the left side to the right side (or vice versa)
- For shapes with horizontal dotted lines: Mirror the top to the bottom (or vice versa)
- For shapes with diagonal dotted lines: Reflect across the diagonal line at the same angle

Each completed shape should look the same when folded along the dotted line - both halves should match perfectly.
