The commonly consider on group of bisectors are the segment bisector and the angle bisector. A perpendicular bisector is a line which intersects or segments the given line into two equal parts. Sorry for bad english! Therefore, we can find the coordinates of E by adding the vectors AB and AD together to get E The slope of AE, the angle bisector, is therefore: and the equation of AE is We can verify that the slope is correct using trigonometry. &= \frac{\tan(\Phi) + \tan(\Phi')}{1 - \tan(\Phi)\tan(\Phi')} \\ \end{aligned} hX2−(a−b)XY−hY2h(x−p)2−(a−b)(x−p)(y−q)−h(y−q)2​=0=0.​, Expanding it is left as an exercise for you.
