Quadrilateral angle sums and special-quadrilateral properties

\(\square ABCD\) represents a metal plate. Use its angle data

The four angles are interior angles of the quadrilateral

Interior angle \(\angle A\): \(131^\circ\)

Interior angle \(\angle B\): unknown

Interior angle \(\angle C\): \(90^\circ\)

Interior angle \(\angle D\): \(91^\circ\)
