Transcription: A transformation is a change in the position, size, or shape of a geometric figure, such as a triangle. The main transformations are reflection, enlargement, translation, and rotation. Other forms of transformations include stretching and shearing. Reflection, translation, and rotation change the position of the figure. They do not alter the lengths of the sides or the area of the figure, and so are called isometries. Stretching increases the size of the figure along one axis. Shearing is similar to stretching, but the area of the figure remains the same. Enlargement increases the size of the ...
