Given the coordinates (13,3), (19,6), and (13,9) what would be the length of the vertical side in centimeters

First, we need to determine which side is the vertical side. From the given coordinates, we can see that the y-coordinates change while the x-coordinates stay the same, indicating that the vertical side is the one with coordinates (13,3) and (13,9).

To calculate the length of the vertical side, we need to find the difference in the y-coordinates:
Length = |y2 - y1| = |9 - 3| = 6

Therefore, the length of the vertical side is 6 centimeters.
