T.i.P.S.

Students should determine the dimensions of figures when given a scale and identify the scale factor given two figures. Using a given scale drawing, students should be able to recompose the figure into a different scale. Students understand that the lengths will change by a factor equal to the product of the magnitude of the two transformations.
Example
