Front

What is symmetry?

Back

Symmetry is a property where a shape or object can be divided into two identical halves that are mirror images of each other.

Front

What is a line of symmetry?

Back

A line of symmetry is an imaginary line that divides a shape into two identical parts that are mirror images.

Front

How many lines of symmetry does a circle have?

Back

A circle has an infinite number of lines of symmetry.

Front

What is the difference between symmetrical and asymmetrical shapes?

Back

Symmetrical shapes can be divided into two identical halves, while asymmetrical shapes cannot.

Front

How many lines of symmetry does a square have?

Back

A square has 4 lines of symmetry.

Front

How many lines of symmetry does a rectangle have?

Back

A rectangle has 2 lines of symmetry.

Front

What is an example of a shape with exactly one line of symmetry?

Back

A regular triangle (equilateral triangle) has exactly one line of symmetry.

Front

Can a shape have more than one line of symmetry?

Back

Yes, some shapes can have multiple lines of symmetry, such as a square or a regular hexagon.

Front

What is the significance of lines of symmetry in art and design?

Back

Lines of symmetry are often used in art and design to create balance and harmony in compositions.

Front

How do you determine the number of lines of symmetry in a shape?

Back

To determine the number of lines of symmetry, you can fold the shape along different lines to see if the two halves match.
