What is another name for a line that divides a figure into two mirror-image halves?
Line of symmetry ✓
Diameter
Perimeter line
Base line
The fold line that produces two matching mirror-image halves is called a line of symmetry.
A figure has line symmetry if...
it has more than 4 sides
one half is the mirror image of the other half when folded along a line ✓
all its sides are equal
it can be rotated to look the same
Line symmetry means the figure can be folded along a line so both halves match exactly.
How many lines of symmetry does a square have?
1
2
4 ✓
0
A square has 4 lines of symmetry: 2 through the midpoints of opposite sides, and 2 through opposite corners.
How many lines of symmetry does a circle have?
1
4
0
Infinitely many ✓
Any line through the centre of a circle divides it into two matching halves, so a circle has infinitely many lines of symmetry.
