Sample questions

1. A right triangle has legs 9 and 12. Find the hypotenuse.

2. A right triangle has hypotenuse 13 and one leg 5. Find the other leg.

3. Find the distance between points (2, 1) and (8, 9).

4. A rectangle is 8 by 15. Find the diagonal.

5. Do side lengths 7, 24, and 25 form a right triangle?

Answer key preview

1. 15

c² = 9² + 12² = 81 + 144 = 225, so c = 15.

2. 12

b² = 13² - 5² = 169 - 25 = 144, so b = 12.

3. 10

The horizontal change is 6 and vertical change is 8, so distance = √(6² + 8²) = √100 = 10.

Common student mistakes

Placing the hypotenuse on the wrong side of the equation
Forgetting to take the square root after solving for a squared length
Using addition instead of subtraction when the hypotenuse is already known

Build the assessment, not just the questions

MathQuizily helps teachers move from a topic or standard to a printable math test with answer keys, balanced difficulty, and classroom-ready PDF output.

A useful assessment should make the learning target clear, cover the intended skills, and give the teacher enough information to review the result before students see it. The workflow supports short quizzes, chapter checks, diagnostic tests, homework packets, make-up assessments, and equivalent retake versions.

Choose a grade, topic, curriculum context, and difficulty level. The generated PDF includes a student version and a separate worked answer key, so teachers can print, review, and grade without reformatting questions or building solutions from scratch. No student account is required to create or print a test.
