Name Period Pythagorean Theorem Pythagorean Theorem-IF a triangle is a right triangle, THEN the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. That is, in the right triangle shown in the figure to the left, a* + b°=c. Prove the Pythagorean theorem. Hint: Find the area of the large square above using sides a, b, and c (as labeled) two diferent ways. For a triangle, A =- bh and for a square, A = s'. Remember that the area of the large square will not change from one calculation to the next Proof:

(2)の解答がわからないです。AQARが等距離になるのって、IQとIRが同じだからとなるのは何故ですか💦

うことである。点IがZQARの2辺AQ, AR から等距離にあることをいえばよい。 Iから,辺 BC および辺 AB, ACの延長にそれぞれ垂線IP, IQ, IR を下ろし、これら (2) 言い換えると「ZB, ZCの外角の二等分線と ZAの二等分線は1点で交わる」とい △ABC のZB, ZCの外角の二等分線の交点をIとする。このとき,次のこと (1) Iを中心として,辺 BC および辺 AB, ACの延長に接する円が存在する。 基本 例題73 証明せよ。 (類広島修道大 (2) ZAの二等分線は,点Iを通る。 墓本 を利用する。 指針>(1) 点PがZAOBのニ等分線上にある →点PがZAOBの2辺OA, OB から等距離にある の線分の長さが等しくなることを示す。 なお,(1)での円を △ABCの 傍接円 といい, 点Iを頂角A内の 傍心 とい。。 解答 Iから,辺BCおよび辺 AB, ACの延長にそれぞれ垂線IP, IQ, IR を下ろす。 (1) IB は ZPBQの二等分線であるから IC は ZPCR の二等分線であるから IP=IQ MO A IP=IR MO MO よって IP=IQ=IR D8 B また,IPIBC, IQLAB, IRLCAであるから, Iを中心とし て,辺BCおよび辺 AB, AC の延長に接する円が存在する。日効日 口(2)(1)より, IQ=IR であるから,点Iは ZQAR の2辺DA AQ, AR から等距離にある。 ゆえに,点IはLQARの二等分線上にある。 したがって, ZAの二等分線は, 点Iを通る。 I の

34. Hは辺 AB上の点であるから, tを実数として OH=ta+(1-)b (0<t<1)と表される。 AB=4から6-a=D4° 2 ゆえに,b|-2a·b+la|"=16であるから 2°-24-b+(/10)=16 したがって a.石=-1 OHLABであるから OH.AB=0 よって OH-AB={ta +(1-:信-石) da+(1-)b+(2t-1)a·b =-10t+4(1-t)ー(2t-1)=-16t+5=0 |2 ニー 5 ゆえに,t= 16 であるから OH=4+。 11 一 -b 16 16
