Question

line symmetry — quiz — level d
which shape has 4 lines of symmetry?

Explanation:

Step1: Analyze trapezoid symmetry

The isosceles trapezoid has 1 line of symmetry, dividing it vertically through the midpoints of the top and bottom sides.

Step2: Analyze parallelogram symmetry

The non-rectangular parallelogram has 0 lines of symmetry; it only has rotational symmetry.

Step3: Analyze square symmetry

The square has 4 lines of symmetry: 2 vertical/horizontal through midpoints of opposite sides, and 2 diagonal lines connecting opposite corners.

Step4: Analyze rectangle symmetry

The non-square rectangle has 2 lines of symmetry: vertical and horizontal through midpoints of opposite sides.

Answer:

The blue square (bottom-left shape)
