Front

What is a line of symmetry?

Back

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

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 circle have?

Back

A circle has an infinite number of lines of symmetry.

Front

Is a triangle symmetrical?

Back

It depends on the type of triangle. An equilateral triangle is symmetrical, while a scalene triangle is not.

Front

What does it mean if a shape is not symmetrical?

Front

Can a shape have more than one line of symmetry?

Back

Yes, a shape can have multiple lines of symmetry, like a rectangle which has 2.

Front

What is rotational symmetry?

Back

Rotational symmetry is when a shape can be rotated around a center point and still look the same.

Front

Give an example of a shape with rotational symmetry.

Back

A star shape can have rotational symmetry if it looks the same after a certain degree of rotation.

Front

How do you determine if a shape is symmetrical?

Back

You can fold the shape along a line to see if both halves match perfectly.
