Question

Choose which statements are true:

I. Every parallelogram is a rhombus.

II. Every rhombus is a parallelogram.

III. Every quadrilateral has 4 sides.

Answer 1

II. Every rhombus is a parallelogram.

III. Every quadrilateral has 4 sides.

Explanation:

Not all parallelograms are rhombuses because a rhombus needs to have equal sides, but a parallelogram does not.

The definition of a rhombus is "a parallelogram with opposite equal acute angles, opposite equal obtuse angles, and four equal sides" so all rhombuses are parallelograms.

The definition of a quadrilateral is having four sides, so all quadrilaterals will have four sides.
