On the way to school, Bobby noticed the school bus travels 8 miles north, then turns west and goes 6 miles to get to school. If there were a road that went straight from Bobby's house to school, how long the road would be?

Use the Pythagorean Theorem.

a^2 + b^2 = c^2

If you sketch this you will see a right triangle is formed.

a = 8

b = 6

c = hypotenuse

Use the Pythagorean theorem

c^2 = a^2 + b^2

Solve for c, road to Bobby's house
