赤い下線のところがどういう構造になっているか分からないです、教えてくださいm(_ _)m

moving from " (1) 点) There are historians and others who would like to make a neat division between "historical facts" and "values." The trouble is that values even enter into deciding what count as facts-there is a big leap involved in 'raw data" to a judgement of fact. More important, one finds that the more complex and multi-levelled the history is, and the more important the issues it raises for today, the less it is possible to sustain a fact-value division. But this by no means implies that there has simply to be a conflict of prejudices and biases, as the data are manipulated to suit one worldview or another. What it does mean is that the self of the historian is an important factor. The historian is shaped by experiences, contexts, norms, values, and beliefs. When dealing with history, especially the sort of history that is of most significance in philosophy, that shaping is bound to be relevant. As far as possible it needs to be articulated and open to discussion. The best historians are well aware of this. They are alert to many dimensions of bias and to the endless (and therefore endlessly discussable) significance of their own horizons and presuppositions. A great deal can of course be learned from those who do not share our presuppositions. Our capacity to make wise, well-supported judgements in matters of historical fact and significance can only be formed over years of discussion with others, many of whom have very different horizons from our own. It is possible to I have a 12-year-old chess champion or mathematical or musical genius, but it is unimaginable that the world's greatest expert on Socrates could be that age. The difficulty is not just one of the time to assimilate information; it is (2)

(1)の証明が解答と少し違ったのですが、この証明の仕方でもあっていますか?

508 基本 例題 106 三垂線の定理 平面αとその上にない点Aがあり,また,α とl上にない点があるとする。 l上の1点をBとするとき, ABLE, OB1l, OALOB 51 OALa が成り立つことを証明せよ。 指針 2000000 中の 基本事 1 多 平 CTA a BU 0 基本105 2 この例題106 と下の練習106 は, 三垂線の定理と呼ばれる。 OA⊥αを証明するには, 直線 OA が 平面α 上の交わる2直線に垂直であることを えばよい。 しかし, 仮定の OA⊥OB 以外に, α上の直線でBを通り OAと垂直と 別解 OA が平面α上の交わる2直線に垂直であることを示すのに, 三平方の定理の るものがほしい。そこで,直線ℓに着目。まず,OALℓを示すことから考えよう。 逆を利用する方法もある。 AB⊥l, Oil であるから, 直 解答 l は平面 OAB に垂直である。 AB, OB は平面 OAB 12 3 よって OALl このことと, OA⊥OB から, 直 線 OA は平面α上の交わる2 直線l, OB と垂直である。 a B ゆえに OA+α 別解 直線 l 上に, Bと異なる 点Cをとる。 三平方の定理から AB2+BC2=AC2 BC2+OB2=OC2 OA2+OB2=AB2 ① ② ③ から 上の交わる 2直線。 直線lと直線OB は点 B で交わる。 L A A AABC AOBC a B (3) l AOAB OA2+OC2=AC2 ゆえに, 三平方の定理の逆により ②から 同 BC²=OC²-OB² ③に代入す ∠AOC=90° すなわち OA+α このことと, OA⊥OBより, 直線 OA は平面α上の交 わる2直線 OB, OC と垂直であるから OALOC あると OA²+OB²+OC²-OB =AC²
