Question

Which of the following are quadrilaterals (select all that apply)?

trapezoids
rectangles
polygons
squares
parallelograms

Answer 1

Trapezoids, rectangles, squares, and parallelograms are
ALWAYS quadrilaterals. (So are kites and rhombera.)

Polygons are quadrilaterals when they happen to have 4 sides.

Answer 2

Answer: The answer is trapezoids, rectangles, squares and parallelograms.

Step-by-step explanation: We are given four options out of which we are to select those which are quadrilaterals.

We know that the quadrilaterals are polygons having four sides.

Trapezoids, rectangles, squares and parallelograms are quadrilaterals having four sides, so theses are the correct answers.

Since a polygon may have any number of sides greater than or equal to 3, so this option is incorrect.

Thus, the correct answer is Trapezoids, rectangles, squares and parallelograms.
