7-6 Dilations and Similarity in the Coordinate Plane - GEOMETRY

The video tutorial covers the concept of dilations and similarity in the coordinate plane. It explains how dilations involve enlarging or reducing a shape while maintaining its form, using examples like optometry. The tutorial discusses preimage and image, scale factors, and how to apply them to coordinates. It also covers finding coordinates of similar triangles using proportions and matching lengths. The video concludes with methods to prove triangle similarity using congruence and similarity criteria.

How do you determine if two triangles are similar?

What is the significance of using proportions when working with similar triangles?

Explain how to use the distance formula to compare triangles.
