Properties of Quadrilaterals: Practice Questions for 11+
19 October 2026
Understanding quadrilaterals
Quadrilaterals are four-sided shapes, each with its own set of properties. For the 11+, children are often asked questions about parallelograms, rectangles, rhombuses, trapezia, and kites. It's important to recognise each type and recall their key features.
Finding missing angles
Many practice questions focus on calculating unknown angles. For example, if one angle in a parallelogram is 130°, children need to remember that opposite angles are equal, and adjacent angles add up to 180°. This helps them set up simple equations to find missing values.
Applying properties in problem solving
Questions may also ask children to use properties such as equal sides, parallel lines, or symmetry. For instance, in a kite where two angles are given and the other two are equal, children can use the fact that the angles in any quadrilateral add up to 360°.
Key insight: Focus on application, not proofs
11+ questions rarely require children to prove why properties are true. Instead, they are expected to apply known facts about quadrilaterals to solve problems quickly and accurately.
Using algebra in geometry
Some questions combine angles with algebra. For example, if an angle is described as (3x + 12)°, children may need to write and solve equations using the angle sum of 360° or the rules for specific quadrilaterals. Practising these mixed questions builds confidence for exam day.
