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

Which shapes have both a horizontal and vertical line of symmetry?

Back

All shapes can have both a horizontal and vertical line of symmetry, including rectangles, circles, and squares.

Front

How many lines of symmetry does a square have?

Back

A square has 4 lines of symmetry.

Front

What is rotational symmetry?

Back

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

Front

Which shape does NOT have rotational symmetry?

Back

A shape like a scalene triangle does not have rotational symmetry.

Front

How many shapes have exactly one line of symmetry?

Back

Some shapes, like a rectangle, have exactly one line of symmetry.

Front

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

Back

A circle has an infinite number of lines of symmetry.

Front

How many lines of symmetry does a rectangle have?

Back

A rectangle has 2 lines of symmetry.

Front

What is the relationship between lines of symmetry and congruence?

Back

Shapes divided by a line of symmetry are congruent, meaning they are identical in shape and size.

Front

Can a shape have no lines of symmetry?

Back

Yes, some shapes, like a scalene triangle, have no lines of symmetry.
