Pythagorean Theorem

a2 + b2 = c2a = leg b = leg c = hypotenuse

Finding a missing side using Pythagorean Theorem

1. Figure out what side is missing (leg or hypotenuse).

2. Input values into the formula.

3. Solve for the missing variable.­ The inverse of a square (2) is a square root.

Pythagorean Triples"Pythagorean triples" are integer solutions to the 

Pythagorean Theorem. 

Using these can make solving using Pythagorean theorem easier by recognizing the relationship 

between the sides of the triangle.

Find the missing side of the triangle.

A tent is supported by a rope tied to a stake, as shown in the diagram. What is the length of the rope?

Abby has let out 50 meters of kite string when she observes that her kite is directly above Emily. If Abby is 35 meters from Emily, how high is the kite?

A builder needs to add diagonal braces to a wall. The wall is 16 feet wide by 12 feet high. What is the length of each brace?

A pole was blown over in a storm. If the distance between where the pole is in the ground and where the broken piece is touching the ground is 7 feet, and the height from the broken part to the ground is 5 feet. How tall was the pole before it broke?
