Distance in 3D

Author:Catherine Ordway, Manqing Gao
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.
