What attribute do all of the figures in Group B share?

• All of the shapes have more than 4 sides.

What attributes do figures C and D share?

• Both are polygons and quadrilaterals.

• Both are polygons and have at least one right angle.
• Both are quadrilaterals with at least one right angle.

• Both have four sides, two angles, and parallel sides.
• Both have four sides, four angles, and two sets of parallel sides.
• Both have four sides, four angles, and at least one acute angle.

All of the shapes below can be classified as ___________.

• parallelograms
• rhombuses
• rectangles
• squares

Four students were arguing about the figures above.  Which student do you agree with?

• Annabeth - A rhombus can be a square because it has four equal sides and four angles.
• Brenden - A square is a rhombus because it has four equal sides, four angles, and two sets of parallel sides.  A rhombus cannot be a square because it doesn't have right angles.
• Cara - Both figures are quadrilaterals because they have four sides and four angles, but they cannot be polygons.
• David - Both figures are parallelograms because they both have two sets of parallel sides, but they are not quadrilaterals.
