Sample Triangle properties questions

A few of the 37 questions, from easier to harder. Choose your exam board and tier to practise them, with every answer marked.

Question 11 markGrade 2-3
How many equal sides does a(n) scalene triangle have? Write your answer as a word: no, two, or three.
Show the worked solution
A scalene triangle has no equal sides - all three are different lengths.
Question 21 markGrade 4-5
A triangle has one angle of 90°. Classify this triangle by the sizes of its angles.
Show the worked solution
A triangle with one angle of exactly 90° is a right-angled triangle. The other two angles must sum to 90° (since all angles in a triangle sum to 180°), so both are less than 90°.
Question 31 markGrade 4-5
Is an equilateral triangle always an isosceles triangle? Explain your answer.
Question 41 markGrade 4-5

What are the common mistakes in Triangle properties?

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.

Misclassifies a triangle's type from its side lengths or angles
Remember: by sides, triangles are scalene (no equal sides), isosceles (two equal sides), or equilateral (all equal). By angles, they are acute-angled (all angles < 90°), right-angled (one angle = 90°), or obtuse-angled (one angle > 90°).
Misclassifies a basic triangle type (e.g. confuses isosceles with equilateral)
Remember the three names by sides: scalene (no equal sides), isosceles (two equal sides), equilateral (three equal sides).
Assumes not all sides are equal when they are
An equilateral triangle has all three sides equal. This triangle has three different side lengths: 3 cm, 4 cm, and 5 cm.
