Composition of Transformations

Composition of Transformations

• Unit 10 Notes

2
A translation, or glide, and a reflection can be
performed one after the other to produce a
transformation known as a glide reflection.
Sketch the image of ?ABC after the glide
reflection. A ( -1,3 ) , B ( -4,-1 ) , C (
-6,-4 ) Translation ( x , y ) ? ( x 10 ,
y) Reflection in the x-axis
3
When two or more transformations are combined to
produce a single transformation, the result is
called a composition of the transformations.
The composition of two (or more) isometries is an
isometry.
4
Does the order in which the transformation is
performed matter?
