mg by gravity's pull

$N_{1}$ - ground pushing wedge upwards

$N_{2}$ by block on wedge as block pushes wedge and $N_{2}$ will be perpendicular to the surface.

mg by gravity $N_{2}$ by wedge as wedge tries to push block and it will be perpendicular to contact surface.

mg by gravity $N_{1}$ by wedge and perpendicular to contact surface $N_{2}$ , $N_{3}$ by support blocks also perpendicular to surface

I think by now you know why.
