Using a set of points to determine if two triangles are similar to each other

The video tutorial guides students through setting up a graph and labeling points to form triangles. It explores whether a triangle is enlarged or proportional by comparing side lengths. The distance formula is introduced to calculate diagonal lengths, and students learn to check proportionality using cross multiplication. The tutorial emphasizes understanding geometric relationships and applying mathematical formulas.

What were the coordinates used to calculate the distance of AB?

How does the teacher suggest estimating the values of the ratios?

What conclusion does the teacher reach about the proportionality of the triangles?
