Remove material at the end of the angle

Hello

I have an angle on which I want to remove material on one side and at each end.

I created a sketch and drew 1 square at each end but it doesn't work.

Where is my mistake?

Hello

I don't know!!! At home it worked. I'm attaching the play I just totally constrained the sketch.
