Example Card: Finding a Missing Leg
Master finding a missing leg in Grade 9 math — Let's see how the Pythagorean theorem helps us find a missing leg, not just the hypotenuse. Part of Quadratic Functions and Equations for Grade 9.
Key Concepts
Let's see how the Pythagorean theorem helps us find a missing leg, not just the hypotenuse. This example applies the first key idea: using the theorem to solve for an unknown side.
Example Problem Find the missing side length, $x$, to the nearest tenth.
(A right triangle is shown with one leg of length 5, the other leg labeled $x$, and the hypotenuse of length 9.).

Why is 'Finding a Missing Leg' an important Grade 9 math skill?
Remember, you only add when you are looking for the hypotenuse (the longest side).. If you already know the hypotenuse and are looking for a shorter leg, you must subtract!.
