2. Distance Formula
Remember the distance formula for finding the distance between two points?
d = √((x2 – x1)2 + (y2 – y1)2)
EX 1: Find the distance between points at (-3,7) and (2,-5)

3. Another Example
EX 2: Determine whether quadrilateral ABCD with vertices A(3,2), B(2,-4), C(-2,-3), and D(-1,3) is a parallelogram.

4. Midpoint Formula YEAH! Another easy formula!
M = ((x2 + x1)/2, (y2 + y1)/2)
EX 3: Find the coordinates of the midpoint of the segment that has endpoints at (-2,4) and (6,-5)
