This video tutorial by Mr. Holcomb covers lesson three on making scale drawings using the parallel method. It begins with an introduction and overview, followed by an explanation of the opening exercise involving triangle dilation. The video includes three examples: drawing parallel lines, creating a parallelogram, and making a scale drawing with a scale factor. Each example provides step-by-step instructions using tools like a ruler, set square, and compass. The lesson concludes with exercises for practice and verification of results.
