.
Take the sum of squares of the lengths of two shortest sides and compare with the square of the longest side.

The longest side is too short
to be the hypotenuse of a right triangle
with legs as long a the two shorter sides.
Therefore, the largest angle
(the one opposite the longest side)
is smaller than a right angle.
That largest angle is acute,
and so are the other two smaller angles.
The triangle is an triangle.
