Front

What is a line of symmetry?

Back

A line of symmetry is a line that divides a shape into two identical parts 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 halves 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 parts 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

Can a triangle be symmetric?

Back

Yes, an equilateral triangle is symmetric because it has three lines of symmetry.

Front

What is an example of a shape that is not symmetric?

Back

A scalene triangle is an example of a shape that is not symmetric because all its sides and angles are different.

Front

What is the line of symmetry for a rectangle?

Back

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

Front

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

Back

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

Front

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

Back

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