alleryWhich quadrilaterals can have exactly one axis?
ARectangle or rhombus
BSquare or oblong shape
CKite or isosceles trapezoid
DParallelogram or kite
Answer & Solution
Correct answer: C. Kite or isosceles trapezoid
1. Rectangles, rhombi and squares have two or more axes.
2. A kite has one axis along a diagonal and an isosceles trapezoid has one through opposite sides.
3. A general parallelogram has no reflection axis, so the parallelogram pairing fails.
