Prin teorema lui Pitagora rezulta:
[tex] {a}^{2} = {b}^{2} + {c}^{2} \\ {a}^{2} = 16 + 9 = 25 \\ a = 5 \: m[/tex]
Prin teorema inaltimii intr-un triunghi dreptunghic rezulta:
[tex]h = \frac{c \times c}{ip} = \frac{bc}{a} = \frac{12}{5} m[/tex]
Prin teorema catetei rezulta:
[tex] {c}^{2} = m \times a \\ 9 = m \times 5 \\ m = \frac{9} {5} [/tex]
[tex] {b}^{2} = n \times a \\ 16 = n \times 5 \\ n = \frac{16}{5} [/tex]
