Let's find out. If so, the Pythagorean theorm will hold 
So we have:

 16² + 48² ≟ 50²
256 + 2304 ≟ 2500
      2560 ≟ 2500

Nope, not quite!  Drawn to scale it looks like this:



That angle at the top looks like a 90° angle but it's only
about 88°, just a couple of degrees short.

In this question you use Pythagorean theorem, a^2+b^2=c^2. So you plug the numbers in equation. *Remember the bigger length is always the hypothenuse*

^^^^^^^^^use that link^^^^^^^^^ to see the hypothenuse the big length of a triangle. So the formula a^2+b^2 are legs and we use two small number compare to 50 are 16 and 48.
a^2 would be substitute for 16^2 + and b^2 would be substitute for b^2 for 48^2 and c^2 for 50^2.
16^2+48^2=50^2 now we solve
-----------------------------
16*16=256
-----------------------------
48*48=2304
-----------------------------
50*50=2500
-----------------------------
256+2304=2500
-----------------------------
2560=2500 DONE!!!!!
-----------------------------
Yes it is a right triangle because two legs when combined have to be greater than hypothenuse.
