Distance+Formula

__//**Key Terms**//__ Distance formula - is used to measure distance between two any points, (x1,y1) and (x2,y2), using pythagoras theorem. Pythagoras Theorem - describes the relationship of the lengths of the sides of a right angle triangle. Midpoint Formula - use to find the exact or approximent location between two coordinates. Hypotenuse - the side opposite the right angle in a right triangle. It is the longest side on a right triangle. Leg - each of the sides of a right angle triangle.

Distance formula is used to find distances between two points. Distance formula can be used to relate to the real world like for instance, two cars are going to California from different directions. One car goes 3 miles north and 10 miles west, and the other car goes 12 miles south and 8 miles east. How far are the two cars?

You can use distance formula to find the lengths of the side of a geometric figure drawn on a coordinate plane. //ex.//
 * When adding values that are square, use a calculater to add before you round the answer.



//ex.// A large building is on fire. Fire trucks from two different fire stations respond to the fire. One station is 3 mi. east and 2 mi. north of the fire. The other station is 1 mi. west and 4 mi. south of the fire. How far apart are the two fire stations?
