Maximum Size of Square Inscribed in Right Angled Triabgle of Given Base and Height
Maximum Size of Square Inscribed in Right Angled Triabgle of Given Base and Height
The diagram shows a square inscribed inside a right angled triangle.
The equation of the line from O to C is
\[y=x\]
anf the equation of the line BH is
\[y= - \frac{h}{b} x + h\]
. From these we can write
\[c=- \frac{h}{b}c + h\]
,br> Hence
\[c(1+ \frac{h}{b})=h \rightarrow c= \frac{hb}{h+b}\]
.
The square has side
\[ \frac{hb}{h+b}\]
.
