Transformations, Reflections, Isometry & Mapping

Transformations & Reflections

This video explains what transformations are, and most useful, it shows you the step-by-step process for performing reflections! A key skill whether you're in geometry, or pre-calc trying to figure out if a function is even or odd based on it being reflectable across the x- or y-axis. Yes!

Images & Preimages In Transformations

Curious what the terms "image" and "preimage" mean in the context of transformations? Here you go.

Isometry

A quick video explaining what isometry is in transformations. Not too interesting, but it may be on your quiz.

Mapping Rules

This video covers mapping rules, which are a sort of equation-looking way to write down a transformation or function. Things like: (x,y)-->(2x,-y).
