2番の赤線のとこで1番と違って足したら1になるとあるのですがなぜ足すと1になるのですか、よろしくお願いします🤲

[Check] 例題 342 交点の位置ベクトル(2) *** 考え方 △ABCにおいて, 辺AB を2:3に内分する点をP, 辺BC を 3:1 に内分する点を Q, 辺 AC を 2:1 に内分する点をRとする.AB= AC=として,次のベクトルをこを用いて表せ. (1) 直線 PQ と辺 ACの延長との交点をSとするとき, AS ニン +A (2)直線 PR と辺BCの延長との交点をTとするとき, AT①分詰合 (1)点Sは直線AC上にあるので, A$ =s+tc と表したとき,s=0 (2)点Tは直線 BC 上にあるので, AT = s6 +tc と表したとき,s+t=1 解 (1) PQ=AQ-AP AB+3AC 2- = AB)+2 D P AQ は BCを3:1に 内分 PはABを2:3に 内分 4 4 20 4 P, Q, Sは一直線上にあるから, PS=kPQ とおける.
