if the ratio of 3 sides of a triangle is 2:3:4 then the ratio of 3 heights corresponding to those 3 sides is
Giải:
Gọi 3 cạnh của tam giác là a, b, c và các chiều cao tương ứng là h, k, g \(\left(a,b,c,h,k,g>0\right)\)
Ta có: \(\frac{a}{2}=\frac{b}{3}=\frac{c}{4}\)
\(ah=bk=cg\)
\(\Rightarrow2.\frac{a}{2}.h=3.\frac{b}{3}k=\frac{c}{4}.4.g\)
\(\Rightarrow2h=3k=4g\)
\(\Rightarrow\frac{2h}{12}=\frac{3k}{12}=\frac{4g}{12}\)
\(\Rightarrow\frac{h}{6}=\frac{k}{4}=\frac{g}{3}\)
