the pathagorean theroms says
a^2+b^2=c^2
so lets substitute
10^2+18^2 should equal 26^2
so 100 +324 should equal 676
but in this case it doesnt so no it s not a rigth angle triangle

no, it is a scalene triangle.
When you plug in 10, 18 and 26 into a^2 +b^2 = c^2, it doesn't equate.
10^2 + 18^2 = 424 , not 676 (26^2)

26² = 676
10² = 100
18² = 324
Now 324 + 100 â 676 therefore triangle is not right angled.
