すごく当たり前のことを聞いていたらすみません。黒い線で囲まれた部分の赤とピンクの蛍光色の部分がわかりません。方冪の定理でなぜOX•OA=OY•ODが示されると接線の長さが等しいのでしょうか。

を意味する. 良問 【基礎 0.3.9】 (1995TOT 秋 JO 間4) 三角形 ABC の LA の二等分線と辺BCの交点を M とし, LA の外角の二等分線と直線BC の交点を N とする. また, 三角形 ABCの外接円の点Aにお ける接線と 直線BC の交点を K とする. このとき MK =KN を証明せよ。 B db A M /CK となり, MK AK が得られる. また, LCAN = LNAD より a D N 解答図のように,線分 BA のAの方向への延長上 に点Dを取る. 接弦定理より LCAK = LABM で ある. LBAM=LMAC より LKMA= LBAM + LABM =外角 = LMAC + LCAK = LKAM LKNA + LABM = LNAD = LCAN =LKAN+LCAK ba b であるので, LABM=LCAK 各辺から引いて LKNA = LKAN が得られる. したがって AK = KN である. これと MK = AK より MK =KN がわかる. 0 0 注 Kは直角三角形 AMN の斜辺の中点で, その 外心である. 【基礎 0.3.10】 (1995TOT 春 SA 問3) 台形の互いに平行でない2辺を直径とするふたつの 円を考える. 台形の対角線の交点がこのふたつの円 の外にあるとき、 対角線の交点からふたつの円に引 いた4本の接線の接点までの線分の長さは、 すべて 等しいことを証明せよ. 解答 AD // BC である台形 ABCD の 対角線の交 点をOとする. また AB を直径とする円と直線 AC の A 以外の交点を X とし, CD を直径とする 円 T2 が BD と交わる D以外の点を Y とする. 同じ円に対する2本の接線の長さは等しいの で, 0 から T1, T2 に引いた接線の長さが等しい ことを示せばよい。それには、方の定理から。 OX-OAOY･OD を示せばよい。 三角形 AOD と COB は相似であるから, OC OB である. また三角形 OBX と三角形 OCY は相似である。 (なぜなら LXOB = LYOC, LOXB = LOYC = OC OY であり、ゆえに OB OX つまり OX-OA = OYOD となり 0 90° である) よって = OA OY OD OX' 証明が完了した。 B A AS OA OD D C ●アポロニウスの円 2定点A,B までの距離の比が一定値k (≠1) で ある点Pの軌跡は CD を直径とする円である. こ こで C, D は直線AB上にあり、符号付き長さで AC:CB=AD: DB を満たす2点である. このC. DをA,Bの調和共役点と呼ぶ.

II Write a paragraph in ENGLISH answering the question below.100 Wiring inq to viilsliv ( 15 cm × 12 ) Please look at the graph below and describe the main trends that are depicted. What sort of relationship between the amount of plastic waste that becomes an environmental pollutant and the income levels of individual countries can be identified on the basis of the graph? What possible reasons might explain this pattern? g Individual data points represent individual countries with the natural log (ln) of the amount of mismanaged plastic waste in kg per 200 person per day (kg/p/d) plotted against the natural log of the gross national income per person. For example, the point depicting the highest rate of plastic pollution represents Sri Lanka, with In (0.229 kg/p/d) = -1.2 and In ($2,420) = 7.79, while the point depicting the lowest rate of plastic pollution represents Sweden with In (0.001 bebesn kg/p/d) = -6.9 and In ($53,810) = 10.89. -
