The sum of the interior angles of a triangle is __ degrees.相关知识点: 试题来源: 解析 180 根据几何学的基本定理,任意一个三角形的三个内角之和等于180度。这一结论可以通过平行线的性质或利用多边形内角和的公式(n边形内角和为(n-2)×180°)推导得出,其中三角形是n=3的情况,因此其内角和为(3-2...
The sum of the interior angles of a triangle is always 180 degrees. ( ) 相关知识点: 试题来源: 解析 正确 根据几何学的基本定理,任何三角形的三个内角之和始终等于180度。这是欧几里得几何中的一个基本性质,可以通过平行线公理进行证明。无论三角形的形状或大小如何变化,其内角和始终保持不变,因此该命题...
It is known that the sum of the interior angles of a triangle is equal to 180°. This is a property of all triangles. It indicates that an exterior angle of a triangle is equal to the sum of the two interior angles that are not adjacent to it…...
