Pythagorean Theorem: Calculating the Hypotenuse WORKSHEET

After introducing students to the wonder of Pythagoras’ theorem, the best way to get them used to using the formula is to begin with calculating the hypotenuse.

Firstly, students will practice identifying the hypotenuse in section A. Here, there are nine right angled triangles in different orientations, and students must circle each hypotenuse. Then, learners will use Pythagoras’ theorem to calculate the missing hypotenuse in nine more right angled triangles, again in different orientations. All answers are integers to really allow your students to focus on applying the formula.

This write - on worksheet has plenty of space for students to methodically write down the formula and show their work each time.
