It is usually its smallest side
In a triangle, the sum of the angles is always 180 degrees. This is known as the angle sum property of triangles. Additionally, the largest angle in a triangle is always opposite the longest side, and the smallest angle is opposite the shortest side.
in a 30-60-90 right triangle, a right angle is always 90 degrees, the smallest angle has a measure of 30 degrees, and the remaining angle measures 60 degrees.
The shortest side
Well if your talking about a regular triangle (equilateral triangle) it is because if you measure it then it will always equal 60 degrees on each turn. Which then Equals 180 (This is for all triangles).

shortest side
The shortest side of a triangle is opposite to the smallest interior angle.
The angle with the smallest measure is opposite the shortest side. Similarly, the angle with the largest measure is opposite the longest side.
In a triangle the smallest angle is always opposite the shortest side. It will always be an acute angle.
In a triangle, the sum of the angles is always 180 degrees. This is known as the angle sum property of triangles. Additionally, the largest angle in a triangle is always opposite the longest side, and the smallest angle is opposite the shortest side.
angle with the greatest measure
in a 30-60-90 right triangle, a right angle is always 90 degrees, the smallest angle has a measure of 30 degrees, and the remaining angle measures 60 degrees.
