Answer:
Yes, it's a right triangle.
Step-by-step explanation:
We can use the Pythagorean theorem to help.
The theorem states that if a triangle is right, [tex]a^{2} + b^{2} = c^{2}[/tex].
C is the longest side of the right triangle or the hypotenuse.
A and b are the other 2 sides
5 is the greatest so that must be [tex]c[/tex].
4 and 3 are [tex]a[/tex] and [tex]b[/tex]. (It doesn't matter which is a and which is b)
Plug in the numbers:
[tex]4^2 + 3^2 = 5^2[/tex]
Solve:
16 + 9 = 25
25 = 25
This triangle is a right triangle!
