Which describes a rhombus?

• has all right angles

• has all acute angles

• has all equal sides

• has all obtuse angles

A rhombus has these characteristics:

-opposite sides are parallel

-all four sides are the same length

Based on this information, which statement must be true?

• Every square must have these same characteristics

• Every rectangle must have these same characteristics

• Every quadrilateral must have these same characteristics

Samantha states that a parallelogram is always a rhombus. Is she correct?

• Yes, because a parallelogram has opposite angles that are equal in size.

• Yes, because a parallelogram has opposite sides that are equal in length.

• No, because a parallelogram does not have opposite sides that are equal.

• No, because a parallelogram does not always have 4 equal sides.

Into which category can a trapezoid be placed?

• parallelogram

• quadrilateral

• rectangle

• rhombus

A square, a rectangle, a trapezoid, and a rhombus all belong to which group of shapes?

• squares

• parallelograms

• quadrilaterals

• regular polygons
