Answer:
This isn't a right-angled triangle because 841 can only equal 841.
Step-by-step explanation:
18ft, 23ft, 29ft
let c=29ft, a=18ft, b=23ft
c^2=a^2+b^2
29^2=18^2+23^2
841=324+529
841=853
Therefore this isn't a right-angled triangle because 841 can only equal 841
=======================================
Explanation:
a = 18, b = 23, c = 29
note: the largest value is always c
Plug those values into the pythagorean theorem
a^2 + b^2 = c^2
18^2 + 23^2 = 29^2
324 + 529 = 841
853 = 841
The last equation is false, so the first equation is false when (a,b,c) = (18,23,29). Meaning that we do not have a right triangle.
----------
In contrast, something like a 3,4,5 triangle is a right triangle because...
a^2 + b^2 = c^2
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25
that true equation means the original equation is true for (a,b,c) = (3,4,5)
