- 1.Write down how many right angles a rectangle has.
- 2.Write down the name given to a triangle whose three sides are all the same length.
- 3.Write down which one of these statements about quadrilaterals is true.
- 4.Quadrilateral WXYZ has WX parallel to ZY, and WZ = XY (the two non-parallel sides are equal in length). Give a reason why angle W = angle X.
- 5.Two sides of a triangle are 9 cm and 15 cm long. Write down which one of these lengths is possible for the third side.
- 6.In kite WXYZ, WX = WZ and XY = ZY (so at each of X and Z, one side from each of the two unequal pairs meets). Angle X = 100°. Work out angle Z.
- 7.Write down the mathematical name for a quadrilateral that has exactly one pair of parallel sides.
- 8.Write down the number of lines of symmetry a rhombus has.
- 9.Write down the name given to a quadrilateral that has exactly one pair of parallel sides.
- 10.A parallelogram has an area of 96 cm² and a base of 8 cm. Work out the perpendicular height of the parallelogram.
- 11.A trapezium-shaped allotment plot has two parallel sides that face each other, and two sloping sides that are equal in length (an isosceles trapezium). One of the angles next to the shorter parallel side is 118°. Work out the angle next to the other end of the same shorter parallel side.
- 12.A tile is described as having two pairs of parallel sides, four equal sides, and diagonals that cross at right angles but are not equal in length. Give a reason why this tile cannot be a square.
- 13.Write down the name given to a quadrilateral with exactly one pair of parallel sides.
- 14.A rhombus has all four sides equal in length. Write down how many pairs of parallel sides a rhombus has.
- 15.In parallelogram ABCD the vertices are labelled in order round the shape, so angle A and angle B are at the two ends of the same side. Angle A is 70°. Work out the size of angle B.
