内角;
noun
the inner of the two angles formed where two sides of a polygon come together
any of the four angles formed in the area between a pair of parallel lines when a third line cuts them
内角
The first known use of interior angle was in 1756
interior anglenoun
any of the four angles formed in the area between a pair of lines when a third line cuts them
1 At this point the initial polygon has been reduced to a triangle, whose interior angle sum is known to be 180 degrees.
2 This is a recursive relationship: The interior angle sum for an n-gon is 180 degrees more than the interior angle sum for an (n − 1)-gon.
3 The result: a round-rimmed pint with an interior angle designed to give your pour the perfect head and aroma every time.
4 With each interior angle measuring 108 degrees, three pentagons leave a gap and four begin to overlap.
5 Dehn focused on the interior angles formed where two faces of a three-dimensional shape meet.
6 Both are three-dimensional structures, but each has a very different geometry: Their layouts are different, the curvature of their exteriors is different, their interior angles are different.
7 Up to a certain sum of the interior angles on one side of the transversal the two lines might indeed meet.
截线一侧两内角到达一定的和数,两直线可能一定相交。
8 The coherence length revised is smaller than the classical, because the revised zenith angle is larger than the launch angle.
修正后的相干长度总比传统相干长度偏小,因为修正后的天顶角比发射角大。
