    Check the Pythagorean theorem, since sqrt(11^2+15^2) does not equal 25 it is not a right triangle. Since two sides are not of equal length it is not an isoceles triangle. Therefore it is a scalene triangle also known as an obtuse triangle.

    @vbroberson A triangle needs to satisfy "the sum of lengths of any two sides must be greater than the third". Which we can be verified by checking the sum of the two \(shorter\) sides i greater than the longest side. In this case, 11+15>25, so it \(is\) a triangle. Also, proof that it is obtuse: \(11^2+15^2=346 < 625=25^2\) so not right-angled either. It's scalene because lengths of all three sides are not equal (so not isosceles nor equilateral).
