Twierdzenie pitagorasa: [tex]a^2 + b^2 = c^2[/tex]
Figura A:
[tex]2^2 + 4^2 = x^2\\4 + 16 = x^2\\20 = x^2\\\sqrt{20} = x\\\sqrt{20} = 2\sqrt{5}[/tex]
Figura B:
[tex]y^2 + 15^2 = 17^2\\y^2 + 225 = 289\\289 - 225 = y^2\\64 = y^2\\\sqrt{64} = 8 = y[/tex]
Figure C:
[tex]Podstawa = 10\\10 :2 = 5\\\\5^2 + h^2 = 8^2\\25 + h^2 = 64\\64 - 25 = h^2\\39 = h^2\\\sqrt{39} = h[/tex]
Figura D:
[tex]6^2 + 8^2 = d^2\\36 + 64 = d^2\\100 = d^2\\\sqrt{100} = 10 = d[/tex]
