<u>Answer-</u>
<em>90°</em><em> is the least angle measure by which this figure can be rotated so that it maps onto itself</em>
<u>Solution-</u>
As the figure has two axis of symmetry, placing x and y axis such that the origin lies on its centroid.
Angle between x axis and y axis is 90°.
So rotating any degree which is a multiple of 90 i.e 90°, 180°, 270°, 360°...... would yield the original figure.
Therefore, 90° is the least angle measure by which this figure can be rotated so that it maps onto itself.
