Finding Missing Edge Lengths on Composite 3D Prisms

This video tutorial teaches how to identify missing edge lengths in composite 3D prisms by locating parallel edges. It begins with a basic example using rectangles to explain that parallel sides are congruent. The tutorial then progresses to identifying parallel sides in composite figures and solving for missing line segments. Finally, it covers working with 3D composite figures made up of rectangular prisms, demonstrating how to use parallel edges to find unknown lengths.
