This video is about scale drawings. It explains how to find the real length of an object based on the measurement of a model of the object.

This video is about similar shapes, which are shapes that have the same corresponding angles but different sizes. The video explains how to find the missing side length of a similar shape by finding the scale factor between the two shapes.
