Asquare rotated about its center by 360 maps onto itself at different angles of rotation

Answer with explanation:

The meaning of rotational symmetry is number of times the geometrical shape appear congruent to itself when it is revolved through a complete circle , that is at different angles less than 360°, number of times the Original Shape and Rotated shape Appear congruent to each other , that will be the Rotational Symmetry of the Geometrical shape.

When a Square is rotated by an angle of 90°, at four times it appears congruent to it's Original Shape.

So, Order of Rotational Symmetry of Square =4

what shape is

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
