If you know the side lengths of a right triangle, can you pretict what the angles will be? #3

I noticed that when you change a side, it also affects the angle. When all sides are equal, all the angles are equal. It is hard to find angles without one given angle. It would be easier to find the angles by using a protractor. If you increase the sides, the angles increase also. if you decrease the sides, the angles decrease. I haven't found a pattern yet. The sides of the triangles are whole numbers. The angles of the triangles are decimals. The angles don't increase or decrease in a certain order.

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

This shows the relationship between 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's measure decreases, but the measure 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.

when looking at the chart above you can see that when the two side lengths are the same, the angles are also the same. since they are both measure 45, you can tell the third angle is 90. looking at the other side lengths that are not the same, you can also see that the angles are different as well. i dont think i would have been able to find those angle measurements when looking at the side lengths.

Lengths: Angles:
AC = 9 A = 45
BC = 9 B = 45

AC = 6 A = 56.31
BC = 9 B = 33.69

AC = 9 A = 29.05
BC = 5 B = 60.95

i noticed that when i changed one of the side lengths of the triangles, the other side length didn't change. on the website, http://www.shodor.org/interactivate/activities/SquaringTheTriangle/,when i changed the side length AC, length BC stayed the same. i noticed that when i changed the side length AC, angle A increases and Angle B decreases. When i increased side BC angle B increased and angle A decreased.
