Symmetry

Front

What is symmetry?

Back

Symmetry is a property where a shape or object is identical on both sides of a dividing line or around a central point.

Front

What are the types of symmetry?

Back

The main types of symmetry are reflective symmetry, rotational symmetry, and translational symmetry.

Front

What is reflective symmetry?

Back

Reflective symmetry occurs when one half of a shape is a mirror image of the other half.

Front

What is rotational symmetry?

Back

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

Front

What is the order of rotational symmetry?

Back

The order of rotational symmetry is the number of times a shape fits onto itself during a full rotation of 360 degrees.

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 rectangle have?

Back

A rectangle has 2 lines of symmetry.

Front

How many lines of symmetry does an equilateral triangle have?

Back

An equilateral triangle has 3 lines of symmetry.

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a shape rotates.

Front

What are the angles of rotation for a square?

Back

The angles of rotation for a square are multiples of 90 degrees.
