In Nebraska, servers need to be at least 19 years of age in order to sell and serve alcohol, but only 16 to handle and dispose of alcohol containers. This means a 19-year-old can bartend and a 16 year-old-can haul full and empty liquors bottles to and from a Nebraska bar.
A triangle with one interior angle measuring more than 90Â° is an obtuse triangle or obtuse-angled triangle. If c is the length of the longest side, then a2 + b2 < c2, where a and b are the lengths of the other sides. A triangle with an interior angle of 180Â° (and collinear vertices) is degenerate.
If right angled triangle is isosceles then it will have one line of symmetry but if it is scalene then there will be no lines of symmetry. We can say that number of equal sides determines the number of lines of symmetry in a triangle or number of lines of symmetry is equals to number of equal sides in a triangle.
