\(\dfrac{V_{SAMC}}{V_{SABC}}=\dfrac{SM}{SB}\)
Theo hệ thức lượng: \(SA^2=SM.SB\Rightarrow SM=\dfrac{SA^2}{SB}\)
\(\Rightarrow\dfrac{SM}{SB}=\left(\dfrac{SA}{SB}\right)^2\)
\(\Rightarrow V_{SAMC}=\left(\dfrac{SA}{SB}\right)^2.V\)
2.
Ta có: \(\dfrac{V_{SAMN}}{V_{SABC}}=\dfrac{SN}{SC}.\dfrac{SM}{SB}\)
Theo c/m câu a ta có \(\dfrac{SM}{SB}=\left(\dfrac{SA}{SB}\right)^2\)
Tương tự áp dụng hệ thức lượng cho tam giác vuông SAC:
\(SA^2=SN.SC\Rightarrow SN=\dfrac{SA^2}{SC}\Rightarrow\dfrac{SN}{SC}=\left(\dfrac{SA}{SC}\right)^2\)
\(\Rightarrow V_{SAMN}=\left(\dfrac{SA}{SB}\right)^2.\left(\dfrac{SA}{SC}\right)^2.V\)
