Draw the mirror image of the butterfly wing on the right side.
Equilateral triangle: 3 lines, Regular octagon: 8 lines, Scalene triangle: 0 lines
Line of Symmetry: An imaginary line that divides a shape into two identical mirror halves
Bilateral Symmetry: Symmetry across one line (left-right symmetry)
Reflection: Creating a mirror image of a shape across a line of symmetry
Regular Polygon Rule: A polygon with n equal sides has n lines of symmetry
- Observe: Look at the shape carefully for balanced parts
- Test: Imagine folding along potential lines to see if halves match
- Verify: Check if points on one side have corresponding points on the other
- Count: Systematically identify all possible symmetry lines
• Regular n-gon: n lines of symmetry
• Isosceles triangle: 1 line of symmetry
• Equilateral triangle: 3 lines of symmetry
• Rectangle: 2 lines of symmetry
• Square: 4 lines of symmetry
• Circle: Infinite lines of symmetry
• Any shape: Must fold perfectly to have a line of symmetry
Before marking your worksheet, ask yourself: "If I fold this shape along this line, will both halves match perfectly?" If yes, then it's a line of symmetry!
