"What would happen if you changed one side and kept the angles the same? How would the hypotenuse change? What original questions do you have about right triangles?"

The Hypotenuse "BC" had changed but not by to much. I had tried this investigation with the triangle triple, 3-4-5. I had kept 3 the same and the angle was 90 degrees. The difference between the changes of the Hypotenuse was not much, but it changed about 1.0. For example,

AB AC Hypotenuse Angle Differents between AC and BC





4 3 5 90
4 4 5.657 90 0.657
4 5 6.403 90 0.746
4 6 7.211 90 0.808
4 7 8.062 90 0.851
4 8 8.944 90 0.905
4 9 9.849 90 0.925
4 10 10.774 90 0.925
4 11 11.705 90 0.931
4 12 12.649 90 0.944


What i had found out is that if you were to change one side by 2 then the difference would be 2 but if u change it by just 1 the difference would also be 1. One question that i have about right triangles is, Is there any other side lengths, of a right triangle, that are not triples?

  1. Yikes, part of your table ended up off the page, so I can't really see your whole pattern. Your description is not quite specific enough for me to follow without the table. You should check with me about how to make tables in your blog - this is a useful skill and would help make it more clear what you are talking about.

  2. I see how your pattern works for most of the table. However when you changed side AC, 7&8, the hypotenuse did not change by one. It changed by a decimal. Do you think there is a reason for this? Or do you think that those sides just didn't fit your theory?

  3. i realy like the question. i like that you answered your question in detail. i also like how you set up your data, i could see your numbers clearly but i would like you to be a bit more clear on your pattern.
