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.
Acute triangle: In an acute triangle, all angle are less than 90 degrees, so all angles are acute angles.The following is an acute triangle. We can also name triangles using angles and sides at the same time. If a triangle has one right angle and two equal sides, we can call that triangle right isosceles triangle. If a triangle has only acute angles and no equal sides, we can call that triangle acute scalene triangle. If a triangle has two equal sides and one obtuse angle, we can call that triangle obtuse isosceles triangle. Notice that an angle cannot be obtuse and equilateral at the same time.
