Finding the Distance Between two points on a coordinate plane. 1. Ignore the x or y values that are the same.

2. Use the Absolute Values of the x or y values that are NOT the same.

3. Same Quadrant: Subtract

Different Quadrant: Add

Example: Find the distance between the points:

(9, -4) and (9, 2)

(-3, 5) and (-7, 5) help- me dying

Which statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent? a. use the slope formula to prove the slopes of the opposite sides are the same. b. use the slope formula to prove the slopes of the opposite sides are opposite reciprocals. c. use the distance formula to prove the lengths of the opposite sides are the same. d. use the distance formula to prove the midpoints of the opposite sides are the same.
