Triangle Translation and Coordinate Changes

This video tutorial teaches how to solve translation problems on graph paper. It begins with plotting the original triangle ABC using given coordinates. The video explains the translation T of -4 and 7, and demonstrates how to use a T table to calculate new points for the translated triangle A'B'C'. Finally, it shows how to graph the translated triangle on the same graph.
