The bar graph shows the win-loss record for a lacrosse team over a period of three years. Explain how you can apply the Ruler Postulate (Post. 1.1) and the Segment Addition Postulate (Post. 1.2) when interpreting a stacked bar graph like the one shown.


The number of wins increased from year-to-year while the number of losses remained constant, showing improvement by the team.


The number of wins plus the number of losses equals the number of games played each year.


The total number of wins divided by the total number of games gives the winning percentage for the three years.


The two different colors of the bars are used to represent the quantities of wins and losses.
