4th Grade - Lines of Symmetry

Front

What is a line of symmetry?

Back

A line of symmetry is a line that divides a shape into two identical halves that are mirror images of each other.

Front

How can you tell if a shape is symmetric?

Back

A shape is symmetric if it can be divided into two identical parts that are mirror images along a line.

Front

Give an example of a symmetric shape.

Back

A square is an example of a symmetric shape because it can be divided into two equal halves along multiple lines of symmetry.

Front

What does it mean if a shape is not symmetric?

Back

If a shape is not symmetric, it cannot be divided into two identical halves that are mirror images of each other.

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 line of symmetry for a rectangle?

Back

A rectangle has two lines of symmetry: one vertical and one horizontal.

Front

Can a shape have more than one line of symmetry?

Back

Yes, a shape can have multiple lines of symmetry, like a square which has four lines of symmetry.

Front

What is an example of a shape with no lines of symmetry?

Back

An irregular shape, like a random polygon, may have no lines of symmetry.

Front

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

Back

Lines of symmetry are important in art and design as they create balance and harmony in visual compositions.

Front

How do you find a line of symmetry in a shape?

Back

To find a line of symmetry, fold the shape along a line and see if both halves match perfectly.
