Creation of this resource was inspired by a [url=https://twitter.com/gogeometry/status/1005468501757386753]tweet[/url] from [url=https://twitter.com/gogeometry]Antonio Gutierrez[/url] (GoGeometry). [br][br]You can move the [b]LARGE VERTICES[/b] of the triangle anywhere you'd like. [br][br]How would you describe the phenomenon you see here in your own words? [br](Try to do so WITHOUT referencing the tweet). [br][br][b]How can we formally prove what is dynamically illustrated here? [/b]
