3rd Grade Quadrilaterals and Partitioning Shapes Quiz: 10 Questions with Explanations

A RectangleB RhombusC SquareD Triangle

Four equal sides and no right angles make a rhombus. A square would need 4 right angles.

A 3B 5C 6D 4

“Quad” means four, so a quadrilateral has 4 straight sides.

A HexagonB TriangleC RhombusD Pentagon

A rhombus has 4 straight sides. The other shapes have 6, 3, and 5 sides.

A Every rectangle is a square.B Every trapezoid is a rhombus.C Every square is a rectangle.D Every rhombus has 4 right angles.

A square has 4 right angles, so it is a rectangle. A rectangle with unequal sides is not a square.

A \(\frac{1}{3}\)B \(\frac{1}{5}\)C \(\frac{1}{8}\)D \(\frac{1}{4}\)

One of 4 equal parts is shaded, so the fraction is one fourth.

A No, the 3 parts are not equal in area.B Yes, because there are 3 parts.C Yes, because the shape is a rectangle.D Yes, because one part is shaded.

Thirds need 3 parts with equal area. These parts have different widths, so they are not equal.

A \(\frac{1}{7}\)B \(\frac{1}{8}\)C \(\frac{1}{16}\)D \(\frac{8}{1}\)

Each of 8 equal parts is 1 over 8 of the whole.

A SquareB RectangleC RhombusD Trapezoid

4 right angles make a rectangle. If all sides were equal it would be a square.

A \(\frac{1}{2}\)B \(\frac{1}{4}\)C \(\frac{1}{3}\)D \(\frac{2}{1}\)

Two parts with equal area are halves, so one triangle is one half.

A A kite with sides 3, 3, 5, and 5B A square with sides of 4C A rectangle that is 3 by 5D A rhombus with sides of 4

This kite has no right angles and its sides are not all equal. The other three are named shapes.
