Step-by-step explanation:
now all you have to do is find factors which shouldn't be that hard

You either find the gradient or distance and if there are equal, therefore the opp are equal

There is only one requirement for three sides in order to be considered possible in constructing a triangle. That requirement is
<em>The sum of any of the two sides must be greater than the third side</em>
11 + 15 = 26      >      21
11+ 21 = 33       >      15
15 + 21 = 16      >      11
Since all of the combination fulfill the requirement, yes we could create the triangle with those sides.
