has to be a^2+b^2=c^2

What do you mean by that?

  • idku
plug in the biggest side for c, and smaller sides for a and b

triangle with sides a b and c is only a right triangle if: a^2+b^2=c^2

So I put in the answer choices with power to the 2nd?

I say a or b cause the bottom is the smallestr and the 2 sides are the same
anonymous
  • anonymous
Okay.

try the first one the longest side = 13 13^2 = 169 12^2 = 144 5^2 = 25 what do you infer from these results?

What do you mean by infer?

what conclusion do you come to? are these the 3 sides of a right angled triangle or not ?

d

Oh, I'm guessing it is.... I mean I kind of see what you did, and I can tell that the 3 lengths equaled to the right angle... I guess..

  • welshfella
well 13^2 = 12^2 + 5^2 - which can only mean that the triangle is right angled - according to the Pythagoras theorem
welshfella
  • welshfella
the square on the hypotenuse ( largest side) = sum of the squares on the other 2 sides - is only true for right angled triangles
anonymous
  • anonymous
Okay.
welshfella
  • welshfella
in symbols that is c^2 = a^2 + b^2 where c is the hypotenuse
anonymous
  • anonymous
Okay. Thank you!

you might like to check out the other 3 - theres at least one which is a right angled triangle
anonymous
  • anonymous
Okay.
