Statement I . The combined equation of `l_1,l_2` is `3x^2+6xy+2y^2=0` and that of `m_1,m_2 is 5x^2+18xy+2y^2=0` . If angle between `l_1,m_2 is theta`, then angle between `l_2,m_1 is theta` .
Statement II . If the pairs of lines `l_1l_2=0,m_1 m_2=0` are equally inclinded that angle between `l_1 and m_2 `= angle between `l_2 and m_1`.
