The explanation felt a little too rushed and could’ve been lengthened to help give the viewer more time to process that claims being made and the visuals being drawn

I believe the motivation is there, and clarity is quite good too. There is a minor mistake the author found with the help or a commenter and corrected it in the comments. Memorability and Novelty are the lowest points in this video.

Nice Geogebra graphics, they made it a lot easier to understand

I’m feeling dizzy, but the topic itself is good and could be explained with geometrical proof

7.1

Good explanation overall.

This a nice and short video on solving a one exam problem. It would be really useful for students preparing for that exam.

Possible improvement: I guess the figures were done by Geogebra (or something similar), so using the animated features of those systems would make the explanations easier to follow.
