Before we begin the activity, take two minutes to remind yourself the definition of [b]"perpendicular"[/b] and [b]"parallel" [/b]lines.
As you experiment with translation, record your initial observations. CHALLENGE: use "parallel", "perpendicular", and/or "distance" in your answers.
As you experiment with reflection, record your initial observations. CHALLENGE: use "parallel", "perpendicular", and/or "distance" in your answers.
As you experiment with rotation, record your initial observations. CHALLENGE: use "parallel", "perpendicular", and/or "distance" in your answers.
Why do mathematicians call these transformations "rigid"?[br][br](You may look up the definition of rigid if you do not know its meaning.)
