Another transformation introduced to young students is the dilation. Learn quiz geometry math transformations with free interactive flashcards. A dilation is not an isometry since it either shrinks or enlarges a figure. To fix this, i suggest tracing the markings with a pen before making the copies. When a figure slides to a new position without flipping or turning, the transformation is called a translation. Describe each transformation, then write a rule to represent the transformation 1.
