# Internal Division

Share0 Share +10 Tweet0 Internal Division of Line Segments Internal Division an interval in a given ratio is that if the interval $$(x_1,y_1)$$ and $$(x_2,y_2)$$ is divided in the ratio $$m:n$$ then the coordinates are; $$\Big(\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n}\Big)$$ Basic of Internal Division of Line Segments If $$A$$ and $$B$$ are the […]

# Angle Between Lines

Share0 Share +10 Tweet0 Linear Functions – Angle Between Lines If the acute angle $$\theta$$ between two straight lines $$y = m_1 x + A$$ and $$y = m_2 x + B$$, then $$\tan{\theta} = \left|\frac{m_1 – m_2}{1+m_1 \times m_2}\right|$$ Basic of Angle Between Lines Find the acute angles […]
