Dilation of Triangle ABC

The video tutorial explains the process of performing a dilation on triangle ABC centered at point A with a scale factor of 1/4. It covers calculating the distances between points, applying the scale factor to these distances, and finding the new positions of points C' and B'. The tutorial emphasizes understanding the geometric transformation and encourages students to seek further help if needed.
