Transformations Project By Jennifer N, Fassio
Texas Essential Knowledge and Skills (TEKS) The student uses mathematical processes to acquire and demonstrate mathematical understanding. � D identify attributes of two-dimensional shapes using informal and formal geometric language interchangeably; � E classify and sort a variety of regular and irregular two- and three-dimensional figures regardless of orientation or size; and � F create two-dimensional shapes using a variety of materials and drawings. �
Transformation Definition: � Changing a shape using • Turn • Flip • Slide, or • Resize � After any of those transformations (turn, flip or slide), the shape still has the same size, area, angles and line lengths.

Rotation Definition � "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:

Reflection Definition � Every point is the same distance from the central line !. . . and. . . � The reflection has the same size as the original image � The central line is called the Mirror Line. . .

Translation Definition In Geometry, "Translation" simply means Moving. . . �. . . without rotating, resizing or anything else, just moving. � To Translate a shape: � Every point of the shape must move: � the same distance � in the same direction. � �
