Relationship between sides & angles of a RIGHT triangle.

If you know the side lengths of a right triangle, can you predict what the angles will be?

Side AC:999999

Side BC:987654

Hypotenuse AB:1212.04211.40210.81710.2969.849

This chart shows the relationship between the changing of the sides and the angles. One pattern that I noticed is that when you change the size of side AC which is the longer side of the triangle, Angle A decreases in it's size, however the size of Angle B increases. This pattern also works when you change the length of side BC the shorter side of the triangle. Just as the measurement of Angle A, the size of the hypotenuse decreases.

  1. Do you see any pattern in the way that the numbers change? If not, you might want to collect more data. What kind of data do you think would be most helpful? How do you think it would be more helpful to organize your data?

  2. So, what is your final thought about the question you are investigating?
    Based on your data table, do you believe that you could predict what the angles will be,If you know the side lengths of a right triangle?
