How to Figure the Scale Factor for a Quadrilateral Graph

A quadrilateral graph is any graph with a four-sided figure. A scale factor is a multiple that either increases or decreases the size of your original quadrilateral. In order to calculate the scale factor, you need to know the location points on the graph of your original and scaled quadrilateral. This is an important geometry concept because it is one of the basic geometric principles. By learning the basics of geometry, you can then master more complicated math.

Instructions

    • 1

      Find the location of one side of the original quadrilateral and a scaled quadrilateral. For example, assume your quadrilateral has a side on points (1,4) and (9,4). Your scaled quadrilateral has sides at (1,4) and (17,4).

    • 2

      Calculate the size of the sides by subtracting the points from each other. In the example, the size of the original side is 9 minus 1, which equals 8, and the size of the scaled figure is 17 minus 1, which equals 16.

      Divide the scaled length size by the original length size to calculate the scale factor. In the example, 16 divided by 8 equals a scale factor of 2.
