Let a and b be the two shorter lengths and let c be the longest length.
.
If {{{a^2+b^2=c^2}}} then it is a right triangle.
.
If {{{a^2+b^2>c^2}}} then it is an acute triangle.
.
If {{{a^2+b^2<c^2}}} then it is an obtuse triangle.
.
If a=b, it is an obtuse isosceles triangle.
If a or b=c, it is an acute isosceles triangle.
If a=b=c, it is an equilateral triangle.
