Distance in 3D

Welcome to the world of 3D! When using a 3D coordinate plane our coordinates are written as (x, y, z) where z is the "height" or the "up/down" (vertical) plane.  Goal: Find the distance between A and B.
  • Make a prism with LENGTH = 16, WIDTH = 14, and HEIGHT = 8.
Note: if you want to change the height of B click until you see the vertical arrows. If you want to change B horizontally, click the point B until you see horizontal arrows.

Click the checkbox to check your answer.

What differences do you see between 2D and 3D? What do you wonder between 2D and 3D?

Which formula will you use to determine the distance AB?
