[color=#c51414]red represents the square and it's relations.[/color] [color=#1551b5]Blue represents the right triangle and it's relations.[/color] [color=#0a971e]green represents the circle and it's relations.[/color]

[b]adjust the slider[/b] to answer the questions based on observation: 1.) Does one figure always have a larger area than the other figures? If so which one? 2.) Is the growth of any of these figures linear? if so which one? 3.) Can you estimate any proportions when comparing the proportions of any of the figures? (e.g. one area may always be 1/5 the area of another figure)
