Ideal first step for students newly introduced to Pythagoras' theorem, identifying right angle triangles encourages students to use the theorem properly, follow the correct steps, and identify the hypotenuse.

This worksheet is made up of 6 triangles for students to use the theorem on. In addition there are a further 3 problem solving questions where learners are given one length in a right angled triangle and asked to find possible values for the two missing lengths.

Next, see our worksheets on calculating the hypotenuse or a shorter side and several problem solving worksheets involving Pythagoras’ theorem.
