How to determine the scale factor for the dilation of two triangles

The video tutorial explains the concept of proportionality in geometry, focusing on determining if two figures are proportional by comparing the ratios of their sides. It discusses how to calculate the scale factor needed to transform one figure into another, emphasizing that for enlargements, the scale factor must be greater than one. The tutorial provides examples to illustrate these concepts, helping learners understand how to apply them in geometric problems.

What must the value of K be when performing an enlargement?
