Find the bisectors of the angles between the lines l1 x + m1 y + n1 = 0 and l2 x + m2 y + n2 = 0 . Also determine the condition that the bisector of the angle in which the origin lies.​

no, because the sides are not congruent

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
