البرهان الثاني (Info)
نسقط عمود من أي زاوية في المثلث ولتكن A على الضلع المقابل لها يقطعه في N.
من المعلوم أن جيب الزاوية في المثلث القائم الزاوية يساوي النسبة بين طولي الضلع المقابل لها والوتر.
في المثلث ANC
← AN = b sin C
و في المثلث ANB
← AN = c sin B
مما سبق نصل إلى أن c sin B = b sin C ومنها نصل إلى القانون.
