Answer :

To find out if the triangle is a right triangle, we must check if the following equation is true:

[tex](15)^2+(20)^2=(25)^2^{}^{}^{}[/tex]

on the left side, we have:

[tex](15)^2+(20)^2=225+400=625^{}[/tex]

and on the right side, we have:

[tex](25)^2=625[/tex]

since on both sides we get 625, we have that the brace forms a right triangle.
