CCSS.MATH.CONTENT.8.G.B.8
Apply the Pythagorean Theorem to find the distance between two points in a coordinate system.

Pythagorean theorem is a theorem in geometry: the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.

Scott and Mark are rock climbing. Scott is at the top of a 75‑foot cliff, when he throws a 96‑foot rope down to Mark, who is on the ground below. If the rope is stretched tightly from Mark’s feet to Scott’s feet, how far from the base of the cliff (directly below Scott) is Mark standing? Draw a diagram and label it. Then find the missing length. Is the length irrational?
