Something You Didn't Learn About Reflections from School!

An in depth look at reflections in geometry. Also, how do objects transform to preserve congruence? Here is a GeoGebra 3D program that can be used for the classroom: www.geogebra.org/3d/syvjnOK.
Errata: @ 6:24 the equation is correct, but the diagram is a bit off. The adjacent side of the triangle would be r-x where 'r' is the root. Otherwise you can always drop the y-int (amounting to a shift left or right) making it 0 and then the equation follows b/c then the line goes through the origin.

Errata: @ 6:24 the equation is correct, but the diagram is a bit off. The adjacent side of the triangle would be r-x where 'r' is the root. Otherwise you can always drop the y-int (amounting to s shift left or right) making it 0 and then the equation follows b/c then the line goes through the origin.

This is great! Have you seen the recent paper in Geometric Algebra that composes motion as k-reflections? I think you'd really like it. The paper is called "Graded Symmetry Groups: Plane and Simple"

Thanks so much. I will definitely check out that paper.

“Plane and simple” 😂😂😂 humanity has fallen

Cool!

Nice video, keep it up
