The video tutorial explains how Eduardo rotates triangle ABC 90 degrees clockwise about the origin to form triangle A'B'C'. It discusses the transformation rules for coordinates, showing how the x and y coordinates change during the rotation. The tutorial sets up a table to compare pre-image and image coordinates, identifies patterns in the transformation, and derives a rule for the 90-degree clockwise rotation: the new x-coordinate is the old y-coordinate, and the new y-coordinate is the negative of the old x-coordinate.
