Question

which quadrilateral is equiangular but not always equilateral? parallelogram square rhombus rectangle

Explanation:

• A parallelogram has opposite angles equal but not all angles are necessarily right angles (so not always equiangular).
• A square is both equiangular (all angles 90°) and equilateral (all sides equal).
• A rhombus has all sides equal but its angles are not necessarily right angles (so not equiangular).
• A rectangle has all angles equal to 90° (equiangular) but its length and width can be different, so it is not always equilateral (only when it's a square, but a rectangle doesn't have to be a square).

Answer:

D. rectangle
