Question

which polygon will always have 4 - fold reflectional symmetry and order 4 rotational symmetry? rectangle trapezoid right triangle square

Explanation:

A rectangle has 2 - fold reflectional symmetry and order 2 rotational symmetry. A trapezoid may have no or 1 - fold reflectional symmetry and usually no rotational symmetry. A right - triangle may have no or 1 - fold reflectional symmetry and no rotational symmetry. A square has 4 lines of symmetry (4 - fold reflectional symmetry) and can be rotated by 90°, 180°, 270° and 360° about its center (order 4 rotational symmetry).

Answer:

D. square
