1 Polygons in the Coordinate Plane 33 22 11 Techniques Examples Practice Problems

2 Distance Formula  Used to determine:  Sides are congruent  Diagonals are congruent 2

3 Midpoint Formula  Used to determine:  Coordinates of the midpoint of a side  Whether diagonals bisect each other 3

4 Slope Formula  Used to determine:  Opposite sides are parallel  Diagonals are perpendicular  Sides are perpendicular 4

5 Tips for Solving  Draw a sketch (plot points)  This helps define sides  The product of perpendicular slopes is -1  Congruent slopes show sides are parallel 5

6 Example 1 6

7 Example 2 7
