What are dilations

The video tutorial covers geometric transformations, focusing on dilation. It begins with a review of rigid transformations like rotations, reflections, and translations, which do not alter the size or shape of figures. The tutorial then introduces dilation, a transformation that changes the size of a figure while maintaining its shape. The concept of a fixed point in dilation is explained, followed by a practical example using a triangle. The video concludes with a visual demonstration of how dilation can enlarge or reduce a figure, emphasizing the importance of understanding scale factors.
