distance formula on a coordinate plane. You know that the distance A B between two points in a plane with Cartesian coordinates A x 1 y 1 and B x 2 y 2 is given by the following formula. Consider a cell tower at the location -2 4 on the coordinate plane with a coverage radius of 3 miles Note that every point 3 miles away from the cell tower will be on the boundary of the cell coverage This will form a circle around the point -24 with a radius 3 units long.

Find the distance between 12 and -30 Find the distance using the Pythagorean Theorem. Length between two points based on a right triangle. You can use the Distance Formula to find the length of such a line.
Applications of the Distance Formula.
In a 3D coordinate plane the distance between two points A and B with coordinates x 1 y 1 z 1 and x 2 y 2 z 2 can also be derived from the Pythagorean Theorem. This indicates how strong in your memory this concept is. The Pythagorean Theorem a2 b2 c2 a 2 b 2 c 2 is based on a right triangle where a and b are the lengths of the legs adjacent to the right angle and c is the length of the hypotenuse. Accepts positive or negative integers and decimals.
