Real Symmetry practice questions

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.
