Unknown Side Lengths in Right Triangles Worksheets
Upskill with our free printable finding the unknown side lengths in right triangles worksheets! What is the length of the longest side of a right triangle whose legs are 8 units and 15 units in length? It's 17 units! We simply plugged the values in the Pythagorean equation and solved it. Now, what if the length of a leg goes missing? You're right! We rearrange the equation with the unknown length as the subject and press on as usual. To boil that down to formulas, we say c = √ (a2 + b2), a = √ (c2 - b2), b = √ (c2 - a2), where a and b are the leg lengths and c is the length of the hypotenuse. Everything will now go swimmingly when you obtain the missing side length of a right triangle!
