“Geometry: An Interactive Journey to Mastery” S:1 E:24 Introduction to Scale

S:1 E:24 Introduction to Scale If you double the side-lengths of a shape, what happens to its area? If the shape is three-dimensional, what happens to its volume? In this lecture, you explore the concept of scale. You use this idea to re-derive one of our fundamental assumptions of geometry, the Pythagorean theorem, using the areas of any shape drawn on the edges of the right triangle – not just squares.
