- 1.Write down the number of lines of symmetry a rhombus has.
- 2.In an isosceles triangle each of the two base angles is 46°. Work out the size of the angle at the apex.
- 3.The cross-section of a tent is an isosceles triangle. The angle at the top, between the two equal sloping sides, is 62°. The other two angles are equal to each other. Work out the size of each of those two angles.
- 4.Quadrilateral PQRS has angle P = 92°, angle Q = 84° and angle R = 106°. Work out the size of angle S.
- 5.Write down the name given to a quadrilateral that has exactly one pair of parallel sides.
- 6.Write down which one of these quadrilaterals always has diagonals that are equal in length and that cross at right angles.
- 7.A parallelogram has an area of 96 cm² and a base of 8 cm. Work out the perpendicular height of the parallelogram.
- 8.Write down how many right angles a rectangle has.
- 9.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.
- 10.Write down which one of these statements about quadrilaterals is true.
- 11.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.
- 12.A rhombus has all four sides equal in length. Write down how many pairs of parallel sides a rhombus has.
- 13.Write down the mathematical name for a quadrilateral that has exactly one pair of parallel sides.
- 14.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.
- 15.ABCD is an isosceles trapezium. The sides AB and DC are parallel, and the two sloping sides AD and BC are equal in length. Angle D is 112°. Work out the size of angle B.
