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 parts that are mirror images of each other.

Front

Is a square symmetric?

Back

Yes, a square is symmetric because it can be divided into two identical halves along multiple 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 that is not symmetric?

Back

An example of a shape that is not symmetric is a scalene triangle.

Front

Can a shape have more than one line of symmetry?

Back

Yes, some shapes can have multiple lines of symmetry, like a circle which has infinite lines of symmetry.

Front

What does it mean if a shape is symmetric?

Back

If a shape is symmetric, it means that it can be divided into two equal parts that are mirror images of each other.

Front

Is a triangle always symmetric?

Back

No, not all triangles are symmetric. Only isosceles and equilateral triangles are symmetric.

Front

What is the line of symmetry for a heart shape?

Back

The line of symmetry for a heart shape is a vertical line that divides it into two equal halves.

Front

How can you determine if a shape is symmetric?

Back

You can determine if a shape is symmetric by folding it along a line and checking if both halves match.

Front

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

Back

An example of a shape with one line of symmetry is an isosceles triangle.
