Composition of transformations (1)
This transformation is a composition of a reflection over the x-axis upon shape ABCD and a rotation of 220 degrees counterclockwise upon shape A'B'C'D' around point G. Refer to the worksheets specifically describing the process of proving accuracy without a coordinate grid in reflections and rotations. What makes compositions different is that there is sequence. After performing one translation the next one in the sequence is performed on the image of the first transformation. Above, a reflection is performed on shape ABCD and then a rotation is performed on shape A'B'C'D', the same shape is not being transformed, but congruent shapes with corresponding sides and angles are.
