Step-by-step explanation:

Equilateral triangle- Centre of rotation= Intersection point of medians= 3

Rectangle objects have Order 2 rotational of symmetry. Rectangle is a special kind of quadrilateral, which has equal opposite sides and all angles of rectangle are of 90 degrees

Pentagon is a 5-sided figure, so it contains five lines of symmetry. For rotation symmetry, the order of any regular polygon is the number of sides. The angle of rotation would be 360 degrees divided by that order.
