Question 796496
<pre>
Let's find out. If so, the Pythagorean theorm will hold 
So we have:

 16² + 48² &#8799; 50²
256 + 2304 &#8799; 2500
      2560 &#8799; 2500

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

{{{drawing(400,1200/7,-10,60,-10,20,
red(arc(48cos(.3254717095),48sin(.3254717095),10,-10,202,289)),

triangle(0,0,48cos(.3254717095),48sin(.3254717095),50,0) )}}}

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