正棱锥是中学数学立体几何中一个重要的内容,现在我们来研究其相邻侧面所成角的关系.给出如下命题:正n棱锥P-A1A2……An(n≥3)中,若相邻侧面所成角为γ,侧棱与底面所成角为θ.
Positive pyramid is an important content in the solid geometry of high school mathematics, and now we study the relationship between the angles formed by its adjacent sides. The following proposition is given: In positive n-pyramid P-A1A2 ...... An (n≥3) The angle formed by the adjacent sides is γ, and the angle between the side edges and the bottom surface is θ.
