赤線部のACのことで、なぜ両辺をACで割ってはいけないのでしょうか？ △ABCは...とあるのでAC≠0だと思いますし、ACで割った結果AC＝ABで二等辺三角形になるとおもったのですが...

次の等式を満たす △ABC は、どんな形の三角形か。 PR 33 AB・AB=AB・AC+ BABC+CA CB 等式を変形すると AB・AC-AB BC+AC・BC-AB・AB=0 この等式の左辺について (左辺)=(AB・AC+AC・BC)-(AB・BC+AB・AB) ○ ○ と、点P (AB+BC) AC(AB+BC)-AB =AC・AC-AB・AC MACARCARE UC =AC (AC-AB) =AC BC ₁5√ √ 25=8-- よって (2AC・BC=0 AC = 0, BC ¥0 であるから したがって AC⊥BC ゆえに, ABC は, ∠C=90°の直角三角形である。 別解 AB・AB=AB(AC+CB)+CA・C ACIBC よって CA ¥0 CB ≠ 0 であるから CB≠0 始点をAにそろえる OCALCR CA⊥CB 等式の右辺において、 =AB・AB+CA・C インタ真空 AB・AC+BA・BC des CA CB=0/200 (s) AC, AB でくくる。 ACでくくる。 12----1--0- したがって CA⊥CB は ゆえに,△ABC は, ∠C=90°の直角三角形である。 =AB・AC-AB・(-CB) と変形する。 +80⁹-00 E+D (AO+HOE) 他の柑介変数表示を媒介変数として求めよ。 また, t を消去した式で表せ。 平行な直線 +70% (1)
