TRANSFORMATIONS
I. TRANSLATION slides each point of a figure the same distance in the same direction. A. EVERYDAY examples... 1) exterior buildings 2) windows. B. link to... COORDINATE examples C. Interactive PRACTICE — TRANSLATIONS II. REFLECTION flips a figure over a mirror or symmetry line. A. EVERYDAY examples... 1) lake images 2) mirrors B. link to... COORDINATE examples C. Interactive PRACTICE — REFLECTIONS III. ROTATION turns a figure about a fixed point at a given angle and a given direction. A. EVERYDAY examples... 1) flower petals 2) Earth axis. B. link to... COORDINATE examples C. Interactive PRACTICE — ROTATIONS D. Math Videos: 1Video: Easy way to do a basic rotation using tracing paper (or clear plastic). This rotation used (0,0) as the rotation point and rotated 90° clockwise. 2Video: Understand point basics of ROTATION around the origin (0,0) IV. DIALATION changes the size of an object, but not the shape. A. EVERYDAY examples... 1) model cars 2) Barbie dolls B. link to... COORDINATE examples C. Math Videos: 1Video #46339: Dilation Examples in Real Life 2Video #1357: Prove two figures are similar after a dilation 3Video #46130: Determine whether the graph represents a dilation. 4Video #1357: Two figures are SIMILAR after a Dilation.
