Map scale is important for understanding maps both in paper and computer form, so it will pay you to understand the types and uses of scales. The two triangles below are congruent and their corresponding sides are color coded. One of the small figures is a square, so it does not have the same shape as the original rectangle, which is not a square. The angles in the scale diagram match the angles in the given diagram.
Also, each side of the smaller quadrilateral increases by the Answers Investigation 3 Applications 1. We would only need the corresponding dimensions of the original and the desired reduction--height, for example--to determine the scaling factor.
