Answers and explanations for all 10 questions

Every answer with the reasoning behind it. Worth reading after you have tried the set — or on its own, if you are a parent marking it.

  1. Which shape has 4 equal sides and 4 right angles?

    Answer: Square

    Only a square has both 4 equal sides and 4 right angles.

  2. How many sides does a hexagon have?

    Answer: 6

    A hexagon has 6 sides and 6 corners.

  3. Which shape has 4 equal sides but no right angles?

    Answer: Rhombus

    A rhombus has 4 equal sides, but its corners are not right angles.

  4. A triangle has all three sides of the same length. What is it called?

    Answer: Equilateral

    An equilateral triangle has three equal sides and three equal angles of 60°.

  5. How many corners does a pentagon have?

    Answer: 5

    A pentagon has 5 sides, and therefore 5 corners.

  6. Which statement about a square is TRUE?

    Answer: Every square is also a rectangle

    A rectangle is a shape with four right angles, and a square has four right angles, so every square is a rectangle.

  7. Which shape has exactly one pair of parallel sides?

    Answer: Trapezium

    A trapezium has exactly one pair of parallel sides.

  8. What do the three angles of any triangle add up to?

    Answer: 180°

    The angles of every triangle add up to 180°, whatever its shape.

  9. A four-sided shape has opposite sides equal and parallel, but no right angles. What is it?

    Answer: Parallelogram

    A parallelogram has both pairs of opposite sides equal and parallel, with slanting corners.

  10. Three angles of a quadrilateral are 90°, 85° and 100°. What is the fourth angle?

    Answer: 85°

    A quadrilateral's angles add to 360°: 90 + 85 + 100 = 275, and 360 − 275 = 85°.
