Determining the scale factor of the enlargement of a triangle

The video tutorial explains how to determine if two triangles are similar by using proportions. It discusses the concept of enlargement and how to calculate the scale factor by comparing the lengths of corresponding sides. The tutorial emphasizes the importance of understanding proportions and provides a step-by-step guide to finding the scale factor, ensuring that students can identify whether a transformation is an enlargement or reduction.
