Transformations Project By: Sophia Cole

Kindergarten TEKS • (A) identify two-dimensional shapes, including circles, triangles, rectangles, and squares as special rectangles; • (D) identify attributes of two-dimensional shapes using informal and formal geometric language interchangeably; • (B) compare two objects with a common measurable attribute to see which object has more of/less of the attribute and describe the difference. • (C) draw conclusions from real-object and picture graphs.

Transformation • Changing a shape using a turn, flip, slide, or resize.

Example of a Transformation

Translation • A translation is moving a shape without changing the object in any other way.

Reflection • A transformation where a geometric figure is reflected across a line. This line is called the “axis of reflection. ”

Examples of a Reflected Figure

Rotation • Movement of an object by holding one point – the center – fixed and rotating the plane about this point by a certain angle clockwise or counterclockwise.

Example of a Rotated Figure • This Triangle has been rotated
