Why Move Things Around? - Transformations - 8.2 - Lesson 1

Author: Todd Parks
Description:

Student Outcomes

  •   Students are introduced to vocabulary and notation related to rigid motions (e.g., transformation, image, and map).
  •   Students are introduced to transformations of the plane and learn that a rigid motion is a transformation that is distance   preserving.
  •   Students use transparencies to imitate a rigid motion that moves or maps one figure to another figure in the plane.

Tutorial

What, Why, and How

Transformations such as reflections, rotations, and translations (which are known as 'rigid motions'), all move objects but maintain the congruence of the original figure.

Reflection: to flip

Rotation: to turn

Translation: to slide
