About this worksheet

Rectangles, rhombuses and squares. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

I can say which diagonal facts belong to rectangles, rhombuses and squares, and that every square is both a rectangle and a rhombus.
I can use those facts to write and solve an equation, then find the angle or length asked for.

Standard: G-CO.C.11

Words to know

rectangle: A parallelogram with four right angles; its diagonals are equal.

rhombus: A parallelogram with four equal sides; its diagonals cross at right angles.

square: Both a rectangle and a rhombus: four right angles and four equal sides.

perpendicular: Crossing at a right angle (90°).

bisect an angle: Cut a corner into two equal angles.

Common mistakes

Your child mixed up the diagonal facts: a rectangle's diagonals are equal, and a rhombus's diagonals cross at right angles. Draw both shapes with their diagonals and compare.

Your child gave a special diagonal fact to every parallelogram. A leaning parallelogram has diagonals of different lengths that cross at a slant. Draw one and measure.

Your child turned the family around. Every square is a rectangle and a rhombus, but most rectangles and rhombuses are not squares.

What to say

Ask: can you draw a rectangle that is not a square?

Questions parents ask
