The image is a diagram showing an isosceles trapezoid with marked congruent sides and angles.
The image contains a geometric shape, specifically an isosceles trapezoid. The trapezoid is drawn with bold black lines. The top base is marked with arrows indicating parallel lines. The two non-parallel sides are marked with three short, parallel orange lines, indicating they are of equal length. The bottom base is also marked with an arrow, indicating it is parallel to the top base. The two base angles on the left and right side are marked with arcs of blue indicating congruence. The two angles at the top are marked with concentric green arcs, demonstrating their congruence. The overall atmosphere is neutral and purely mathematical; there is no emotional context or implied mood beyond the technical information presented for geometric analysis.

An isosceles trapezoid has symmetry that allows it to be rotated onto itself. The angle of rotation that achieves this for an isosceles trapezoid is typically 180 degrees. This rotation will align each vertex with the corresponding vertex diagonally opposite it, thereby turning the trapezoid onto itself.
Therefore, a rotation of 180° would turn the figure onto itself.
