 Math 2 Unit 2 Composite Transformations A Composite Transformation is a transformation that consists of more than one step to the transformation. For example, translate an object and then, do a second translation on the product, to again move the object. Also, there can be a combination of two different transformations. For example, translate the object and then perform a size transformation. Here are the components to transform an object more than once: Translation: (x,y)-->(x+a, y+b) (x+a,y+b)--> (x+h, y+k) OR (x,y)-->(x+a+h, y+b+k) Original Image 1st Translation 2nd Translation Rotation: (x,y)-->(-y,x) (-y,x)-->(y,-x) Original Image 1st Rotation 2nd Rotation Reflection: (x,y)-->(x,-y) (x,-y)-->(-x,-y) Original Image 1st Reflection 2nd Reflection Size Transformation: (x,y)-->(2x, 2y) (2x,2y)--> (.25x,.25y) OR 2x.25=.5 (x,y)-->(.5x,.5y) Original Image 1st Size Transformation 2nd Size Transformation
