Title: Strange Shapes | MIT's Science Out Loud
Description:

In school, you learn about shapes with sides and edges, but there are weird shapes out there (beyond our 3 dimensions) that defy our normal idea of geometry. QuanQuan and Jenny explain, knit, and 3D print their way through these strange shapes.

Title: The Origami Revolution | Math and Science Modernize an Ancient Tradition
Description:

Discover parallels between the natural world and origami—the Japanese art of paper folding—and witness how artists, mathematicians, and scientists are pioneering complex new designs, in this video from NOVA: The Origami Revolution. While origami is steeped in tradition, computer programs are being used today to develop new, more complex designs so that almost any three-dimensional object can be translated into a two-dimensional pattern that can be folded to model the object. This resource is part of the NOVA Collection.

Title: Geometry Module 2, Topic C: Similarity and Dilations
URL: https://www.engageny.org/resource/geometry-module-2-topic-c-overview
Description:

Students learn what it means for two figures to be similar in general, and then focus on triangles and what criteria predict that two triangles will be similar. Length relationships within and between figures are studied closely and foreshadows work in Module 2, Topic D. The topic closes with a look at how similarity has been used in real-world application.
