Project Part 5 School Book Page: “Flip, turn, and slide”

TEKS • 3: The student uses the process skills to generate and describe rigid transformations (translation, reflection, and rotation) and non -rigid transformations (dilations that preserve similarity and reductions and enlargements that do not preserve similarity). • 2 nd grade

Transformation • Moving a shape so that it is in a different position, but still has the same size, area, angles and line lengths. • Turn, flip or slide are the basic moves.

Transformation Example

Animation • Great game to visualize slides, flips, and turns! • Click Here • Or: http: //www. harcourtschool. com/activity/icy_ slides_flips_turns/

Translation • A function that moves every point a constant distance in a specified direction. A translation can be described as a rigid motion

Translation Example

Reflection • A transformation in which a geometric figure is reflected across a line, creating a mirror image. That line is called the axis of reflection.

Example

Rotation • "Rotation" means turning around a center: • The distance from the center to any point on the shape stays the same. • Every point makes a circle around the center.
