How can you use the Pythagorean Theorem to find the distance between two points on a coordinate plane?

Example: Find the length of the hypotenuse 4. Plug in those numbers into the P-Theorem and solve.

YOUR TURN: Find the length of the hypotenuse 4. Plug in those numbers into the P-Theorem and solve.

Example: Find the length of the hypotenuse 4. Plug in those numbers into the P-Theorem and solve.

NON-Perfect Square Answers (Irrational Numbers) Sometimes the hypotenuse will not be a square root of a perfect square We will estimate and round to ONE decimal place

Example: Find the length of the hypotenuse 4. Plug in those numbers into the P-Theorem and solve. approximately

Example: Find the length of the hypotenuse 4. Plug in those numbers into the P-Theorem and solve. approximately

4. Plug in those numbers into the P-Theorem and solve. approximately YOUR TURN: Find the length of the hypotenuse

Word Problem: If it is 4 miles from Point X to Point Z, and it is 5 miles from Point X to Point Y, what is the approximate distance from point Y to Point Z?
