G.2 pt. 3 Reflectional & Rotational Symmetry Assessment

Front

Symmetry is ...

Back

when one shape becomes exactly like another if you flip it.

Front

What type of symmetry does a shape with only one line of symmetry have?

Back

Only Line.

Front

Identify the smallest angle of rotation that maps the image to itself: 72°, 180°, 144°, 45°

Back

72°.

Front

What is the order and angle of rotation of a flag with Order 4?

Back

Order 4, 90 degrees.

Front

Which letter does not have line symmetry but has rotational symmetry: H, I, Z, X?

Back

Z.

Front

Define reflectional symmetry.

Back

A shape has reflectional symmetry if it can be divided into two identical halves that are mirror images of each other.

Front

Define rotational symmetry.

Back

A shape has rotational symmetry if it can be rotated around a central point and still look the same at certain angles.

Front

What is the angle of rotation for a shape with Order 3 symmetry?

Back

120 degrees.

Front

How many lines of symmetry does a circle have?

Back

Infinite lines of symmetry.

Front

What is the difference between reflectional and rotational symmetry?

Back

Reflectional symmetry involves flipping a shape, while rotational symmetry involves turning a shape around a point.
