Question

does 4,6,8 forms right angle triangle​

Answer 1

$\huge\boxed{\fcolorbox{black}{red}{ANSWER}}$

Yes

Answer 2

Let's use phythogorean theorem

Let 8 be C the hypotenuse
Let 4 be the arm A
Let 6 be the arm B

(A)^2 + (B)^2 = (C)^2
= (4)^2 + (6)^2 = (8)^2
= 16+36=64
= 52=64
= Hence 52 is not equal to 64

Therefore, 4,6,8 doesn't form a right angled triangle
