Combined Transformation

Mathematics

4 types of transformation

Translation, reflection, rotation and enlargement

Reflection on line, x = 5

Example of reflection

Rotation of 90° anticlockwise at centre (6, 5)

Example of rotation

Enlargement at centre (1, 9) with scale factor 3

Example of enlargement

Congruent image

Images have the same shape and size

Non-congruent image

Images that is similar but different size from the object

Combined transformation AB

Transformation B followed by transformation A

Congruent image orientation

Same shape orientation and inverted shape orientation

Non-congruent image transformation

Enlargement image have similar shape but different size

Order of transformation

Transformation P performed 2 times in a row
