Step-by-step explanation:
Given that,
The side lengths of a triangle are 5,3 and 4.
For a right triangle, the Pythagoras theorem is applicable. We know that, for a right triangle,
[tex]H^2=b^2+h^2[/tex]
Where
H is Hypotenuse
b is base
h is perpendicular height
If we put b = 3. h = 4, then
[tex]H^2=3^2+4^2\\\\H^2=9+16\\\\H=5[/tex]
Hence, it will form a right triangle.
