This grade 8 pythagorean theorem quiz asks 10 multiple-choice questions on the pythagorean theorem, and each answer comes with a short explanation.
Ten multiple-choice questions on the Pythagorean Theorem (8.G.B.6 and 8.G.B.7). Find missing sides, test triangles with the converse, and handle ladders, screens and boxes. Pick the single best answer, then read the explanation to see which mistake each wrong choice matches.
🎉 Quiz complete!
How does this quiz work?
Read each question, choose one answer among A, B, C and D, then check it: a short explanation appears after every answer. Your score out of 10 is shown at the end, and you can restart the quiz as often as you like.
What should you review before the quiz?
Reread the key facts of the lesson and the worked example. If a question is hard, go back to the matching part of the lesson, then try the quiz again. Write your work on scrap paper: most mistakes come from skipping a step, not from the idea itself.
Remember:
- Standards 8.G.B.6 and 8.G.B.7: explain a proof of the theorem and its converse, then apply it in two and three dimensions.
- The hypotenuse is opposite the right angle and is always the longest side.
- To find a missing side, substitute into \(a^{2}+b^{2}=c^{2}\), then take a positive square root.
- Converse: if \(a^{2}+b^{2}=c^{2}\) holds for the sides of a triangle, it is a right triangle.
- The diagonal of a box satisfies \(d^{2}=l^{2}+w^{2}+h^{2}\).
