If z_{1}=1+2i,z_{2}=2+3i,z_{3}=3+4i,then z_{1},z_{2} and z_{3} represents the vertices of

Express (2+3i/ 2-3i)-(2-3i/ 2+3i) in the form of a+ib

The equation of the line joining the points represented by 2-3i and -3+4i in the Argand plane is

ABC is an isosceles triangle and B= 90^{0}. If B and the midpoint P of AC are represented by 3+2i and 1-i then the other vertices are

In the Argand plane, the points represented by the complex numbers 2-i,-4+3i and -3-2i form
