What is the order for the image?

Based on the rotation order, which doesn't belong?

• parallelogram

• rectangle

• rhombus

• trapezoid

Answer explanation

all of the shapes have a rotation order of 2 except trapezoid which only has 1

Which statement is correct based on the two flags?

• Both flags have same rotational order, but different number of lines of symmetry

• Both flags have same number of lines of symmetry, but different rotational order

• Both flags have same rotational order and number of lines of symmetry

• Flags have different number of lines of symmetry and rotational order

Answer explanation

This shape has_____

• only rotational symmetry

• only reflectional symmetry

• both reflectional and rotational symmetry

• neither symmetry

Determine the order and angle of rotation of the figure:

• Order 8, Angle of Rotation 45 degrees
