Symmetry (Lines, Reflective symmetry, Order of Rotation)

Front

What is symmetry?

Back

Symmetry is a property where a shape or object can be divided into parts that are identical or mirror images of each other.

Front

What is reflective symmetry?

Back

Reflective symmetry, also known as line symmetry, occurs when one half of a shape is a mirror image of the other half.

Front

What is the order of rotation?

Back

The order of rotation is the number of times a shape can be rotated around a central point and still look the same within a full 360-degree rotation.

Front

How many lines of symmetry does a circle have?

Back

A circle has an infinite number of lines of symmetry.

Front

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

Back

A rectangle has one line of symmetry.

Front

Which letter has line symmetry?

Back

The letter 'H' has line symmetry.

Front

What is an example of a shape with rotational symmetry of order 2?

Back

A square has rotational symmetry of order 2.

Front

How many lines of symmetry does an equilateral triangle have?

Back

An equilateral triangle has 3 lines of symmetry.

Front

What is the difference between line symmetry and rotational symmetry?

Back

Line symmetry involves a mirror image across a line, while rotational symmetry involves rotating a shape around a point.

Front

Which letter does not have line symmetry but has rotational symmetry?

Back

The letter 'Z' does not have line symmetry but has rotational symmetry.
