Draw lines of symmetry on the objects. Color the butterflies to show symmetry. Identify pictures with symmetry. Count lines of symmetry for shapes.

Here are the solutions to your questions:

3. Draw a line of symmetry on these real life objects.

• Leaf: Draw a vertical line down the center of the leaf, following the main vein.
• Butterfly: Draw a vertical line down the center of the butterfly's body.
• Pattern: Draw a vertical line down the center of the pattern, or a horizontal line across the center.

4. Colour the butterflies to show that they are symmetrical.
This is an instruction for you to complete by coloring the butterflies so that one half is a mirror image of the other half.

5. Which of these pictures have lines of symmetry?
The pictures with lines of symmetry are:

• The top-left pattern.
• The top-right pattern.
• The bottom-right pattern.

6. How many more lines of symmetry can you Identify? What is the total number?

• a. Square: The square has 3 more lines of symmetry (1 horizontal and 2 diagonal). The total number of lines of symmetry is 4.
• b. Isosceles Triangle: The isosceles triangle has no more lines of symmetry. The total number of lines of symmetry is 1.
• c. Regular Pentagon: The regular pentagon has 4 more lines of symmetry. The total number of lines of symmetry is 5.
• d. Regular Hexagon: The regular hexagon has 5 more lines of symmetry. The total number of lines of symmetry is 6.

How many lines of symmetry will a regular octagon have?
A regular octagon has 8 lines of symmetry.

• c.
  • i. 1
  • ii. Draw a horizontal line through the middle of the shape.
• d.
  • i. 0
  • ii. This shape is not symmetrical.
• e.
  • i. 0
  • ii. This shape is not symmetrical.
• f.
  • i. 1
  • ii. Draw a vertical line through the middle of the shape.
