### Making a trapezoidal shape out of a rectangular one?

In the attached drawing I roughly draw what I would like to achieve. Making little trapzoids out of the rectangle, because otherwise, when folding, these "ears" will be conflicting and get in eachothers' way.

Depends on the drawing but this is done with ...
- the "Lengthen / Shorten tool for the horizontal lines,
- the "Tangent Point Circle" tool for the connection between horizontal line and radius,
- the "Break out Segment" tool to clean the transition between radius and line.

I recommend to do it once (lazy me!), copy it to the clipboard and use it for every needed situation.

Thanks. Your solution, though looking nice, is not what I intended. The tangent to the half circle would be a perpendicular line. Think of these trapezoidal "ears" to be bent up by 90°. Then the tangent would result in an unwanted gap. It's a nuance, but important to me.

Regarding to your example and assuming you will bend it to 90 degree then it should be a triangle and not a trapezoid.
