Mechanical engineers, I need help with Orthogonal projection!!

I’m a freshman doing my undergrad in Mechanical engineering and I’m working on an Orthogonal projection drawing assignment.

Is the trapezoidal protrusion symmetrical when looking from the front?

Is the right side orthogonal to the base? Is the back?

I tried drawing shadow lines, projecting the top, but it seems like I can project the top surface to different places on the drawing.

Thank you!
