Creation of this resource was inspired by a problem posted by Antonio Gutierrez (GoGeometry).
You can move the LARGE WHITE VERTICES of the white triangle anywhere you'd like at any time.
Note:
In this animation, dashed lines (soon-to-appear) are parallel to segments to which they appear to be.
Questions:
How can we put into words what is dynamically illustrated here?
How can we formally prove this phenomenon always holds true for this special triangle?
