1. Match up the following list of quadrilaterals with the diagrams below:

trapezium, isosceles trapezium, cyclic quadrilateral, kite, arrowhead, parallelogram, rhombus, rectangle, square.














2. What is the name given to a quadrilateral in which:

(a) All sides are equal and interior angles are equal to 90°?

(b) One set of opposite sides are parallel?

(c) All interior angles are 90° and diagonals do not intersect at 90°?

(d) Diagonals intersect at 90° but no pair of sides are parallel?


3. Find the size of the angles marked by letters:


(a) Rhombus


(b) Kite


(c) Isosceles trapezium


(d) Rectangle

Also find the length of the diagonal, x

(You may need some Year 10 trigonometry!)
