    • Which is the symbol for composition of transformations?

      The symbol for a composition of transformations (or functions) is an open circle. A notation such as is read as: "a translation of (x, y) → (x+ 1, y+ 5) aftera reflection in the line y = x". You may also see the notation written as .


    • When is the composition of a transformation not commutative?

      Composition of transformations is not commutative. As the graphs below show, if the transformation is read from left to right, the result will NOT be the same as reading from right to left. A composition of anytranslationor rotation can be expressed as the composition of two reflections.


    • Which is an example of a composition of rotation?

      A composition of anytranslationor rotation can be expressed as the composition of two reflections. A composition ofreflectionsover two parallel linesis equivalent to a translation.! Example: Given a|| b, and pre-image ΔABC, where parallel lines are vertical.!! ! The composition of reflectionsover two intersecting linesis equivalent to a rotation.!

      2 4.1.1 Definition. Let 1 = (1, 1) and 2 = (2, 2) be two abstract geometries, and let f : 1 → 2 a function that is bijective. Then we say that f is a geometric transformation if f also maps 1 onto 2. In other words, a 1-1 transformation f : 1 → 2 is geometric if takes the set 1 of all points in 1 onto the set 2 of all points in 2, and takes the set 1 of all lines in 1 onto the

      Composition of Transformations A composition (of transformations) is when more than one transformation is performed on a figure. Compositions can always be written as one rule. You can compose any transformations, but here are some of the most common compositions: 1) A glide reflection is a composition of a reflection and a translation.
