triangles

The question i will be discussing is," If you take a right triangle and change one side length how does that change the other length?How does that change the angles of the triangle. As soon as i read this question i had a little clue.
During the weekend my teacher sent me four websites i can use. i mostly used the fourth one. The fourth website helped me the most. Thanks to that website i got this data

side ac Ac measurement bc bc measurement AB AB measurement
9 45 degrees 9 45 degrees 12.12 90 degrees
9 33.69 degrees 6 56.31 degrees 10.81 90 degrees
9 71.57 degrees 3 71.57 degrees 9.487 90 degrees
9 83.66 degrees 1 18.43 degrees 9.005 90 degrees

As you can see as you change one side another side must change this same rule that i made also has to go with the angle measurement because the two angles have to add up to 90

  1. Can you be more specific about your pattern. If you increase one side, does the other side increase or decrease? Does the other side change by a predictable amount? Could you add a picture of the triangle that you are investigating? Does your pattern allow you to make predictions about what will happen?
