Here, sides of the triangle follow the Pythagoras theorem, so it is a "Right-Angle" triangle.

a^2 + b^2 = c^2

Hope this helps!

 Follow the Pythagoras theorem :

5 inches is the longest lenght.

5² = 25
3² + 4² = 9 + 16 = 25

So 5² = 3² + 4²

That means the triangle is a right triangle.

Hope this helps !
