Problem

Compare an isosceles trapezoid with distinct bases to a trapezoid with exactly \(\text{one}~\text{pair}\) of parallel sides that is not isosceles. For each, identify reflection-axis count/type and nonzero rotations below \(360°\); then identify the isosceles-only symmetry.

isosceles trapezoid = 0 axes, rotations none; non-isosceles trapezoid = 1 axis, rotations none; isosceles-only = none

isosceles trapezoid = 1 axis through both base midpoints, rotations none; non-isosceles trapezoid = 0 axes, rotations none; isosceles-only = the base-midpoint reflection

isosceles trapezoid = 1 axis, rotations 180°; non-isosceles trapezoid = 0 axes, rotations none; isosceles-only = axis and 180°

both trapezoids = 1 base-midpoint axis, rotations none; isosceles-only = none
