Product Description
Basic worksheet that presents the Pythagorean Theorem clearly and reinforces concept with problems. Includes definitions and characteristics of right triangles and the Pythagorean theorem. The sheet is pretty self-explanatory so students tend to have minimal questions. Useful for keeping students engaged if you need to do some quick preparation or grading. It is short and appears simple but designed to connect to different activities and fit existing lesson plans.

Students find a missing side for two special triangles using the Pythagorean Theorem. First problem is guided, showing the process of applying the theorem and having the student fill in blanks. This provides a guide for doing the second problem.

Teacher can show how students could find the sides faster by using special triangles - transition to discussion of special triangles: 3 – 4 –5, 5 – 12 – 13, and all triangles similar to those.

Can also have students use a protractor and ruler to measure sides and angles of the triangles (or just give the students the angles and sides). Then, discuss how the largest angle (always the right angle) corresponds to the longest side (the hypotenuse) and the smallest angle corresponds to the shortest side.
