Today in math class we reviewed the scale factor,and similar figures. The scale factor is the number used to multiply the x and y cordinates. For example if the scale factor was two then the x and y cordinates would be multiplied by two times the original cordinates. Similar figures are any shapes that have corresponding angles of equal measurements. For example b is similar to a and the scale factor for a to b is 2.
