Definition of Rigid Transformations (Developing)
Perpendicular and Parallel
Before we begin the activity, take two minutes to remind yourself the definition of "perpendicular" and "parallel" lines.
Translation (any BLUE points can be moved)
Question 1
As you experiment with translation, record your initial observations. CHALLENGE: use "parallel", "perpendicular", and/or "distance" in your answers.
Reflection (any BLUE points can be moved)
Question 2
As you experiment with reflection, record your initial observations. CHALLENGE: use "parallel", "perpendicular", and/or "distance" in your answers.
Rotation (any BLUE points can be moved)
Question 3
As you experiment with rotation, record your initial observations. CHALLENGE: use "parallel", "perpendicular", and/or "distance" in your answers.
Question 4
Why do mathematicians call these transformations "rigid"? (You may look up the definition of rigid if you do not know its meaning.)
