Sample Geometric Proofs questions

A few of the 55 questions, from easier to harder. Choose your exam board and tier to practise them, with every answer marked.

Question 11 markGrade 4-5
Two triangles are congruent by SSS. Explain why it follows that their corresponding angles must also be equal.
Show the worked solution
Congruent triangles are exact copies of each other - one triangle can be placed exactly on top of the other (possibly after a rotation, reflection or translation) so that every point coincides. Because the whole triangle matches exactly, every corresponding pair of sides is equal AND every corresponding pair of angles is equal.
Question 23 marksGrade 5-6
A kite WBFQ has WB = WQ and FB = FQ (so WF is a line of symmetry). Prove, using congruent triangles, that angle WBF = angle WQF.
Show the worked solution

What are the common mistakes in Geometric Proofs?

When a pupil makes one of these on Revision Workshop, the marking engine names the mistake and explains it, instead of just marking the answer wrong.

Adds two values where subtraction was needed
Since 34 m is the hypotenuse and 16 m is one of the shorter sides, you must SUBTRACT to find the missing shorter side, not add - adding would be used only when finding the hypotenuse itself from the two shorter sides.
Reaches the squared value but stops before taking the required square root
81 is missing^2, not the missing length itself - you must take the square root to get the final answer of 9.
Miscounts the number of triangles by one
Drawing diagonals from a single vertex of an n-sided polygon creates (n - 2) triangles, not n triangles.
