$(1+2i)$ is represented by the point $(1, 2)$ on the complex plane

The complex plane is a geometric representation of the complex numbers established by the real axis and the perpendicular imaginary axis.

In this example: $(1+2i)$ has a real part of $+1$ and an imaginary part of $+2i$

$(1+2i)$ can be repesented by a point $+1$ on the real axis and $+2$ in the imaginary axis.

Therefore, this point is $(1, 2)$ on the complex plane.
