WebThe Perpendicularity Lemma droid347 and yojan sushi September 2, 2015 Abstract In this note, we introduce the Perpendicularity Lemma, a simple result that, when applied, can reduce quite a few complex olympiad geometry problems to mere computations. Credits … WebThis lemma implies that s √ = 216. If we let E be the foot of I on AB, then AE = s − BC = 72, consequently the inradius is r = 972 − 722 = 65. Finally, the area is sr = 216 · 65 = 14040 . First Solution. Since OI ⊥ DA, AI = DI. Now, it is a well-known fact that DI = DB = DC (this is occasionally called “Fact 5”). Then by Ptolemy’s Theorem,
