Look at the blue line going from 00 to 30. Since this format always works it can be turned into a formula. Let Px1 y1 and Qx2 y2 be the coordinates of two points on the coordinate plane.
If the distance between the points x 10 and 1 5 is 13 cm then find the value of x.
You have a kite with two sides of length 6 feet and two sides of length 4 feet. The distance formula given above can be written as. Gain an edge over your peers by memorizing the distance formula d x 2 - x 1 2 y 2 - y 1 2. This is precisely the Pythagorean Theorem if we make the substitutions.
