When you rotate it around a point found in the middle of the figure 180 degrees. For example, H does have rotational symmetry however, E doesn't

If a point is at coordinates (x , y), then move it to (-x, -y).

The best way is this:Draw a line from the point closest to the origin to the actual origin. Rotate the line however many degrees you are told, whichever way you are told. After you have the point closest to the origin rotated, you can either rotate the other points the same way or just draw them in based on where the other point lies.Another way, sort of the cheater way, is to just take a piece of tracing paper and trace the figure onto it. Hold it down by pressing your pencil on the tracing paper where the origin is, and rotating it however many degrees, whichever way you are told.This is for ROTATE. To reflect just use the opposite signs on the coordinates.

To find the smallest angle of rotational symmetry for a figure, divide 360 degrees by the number of rotational symmetries of the figure. The result will give you the smallest angle of rotational symmetry.

To turn around a centre point is to rotate.

I dont really know if this is right but i think to do this problem you have to take a point then rotate the paper counter clockwise around the origin then you have a new point which is called a prime. Then reflect it over the y axis on the graph.

A fixed point around which a rod moves is called a pivot point or fulcrum. It serves as a point of support for the rod to rotate or pivot around without translating.

Its called points maybe

The point on which a lever rests or pivots is called the fulcrum. It acts as a point of support for the lever to rotate around, allowing it to lift or move objects.

turn it from the middle

If a point is at coordinates (x , y), then move it to (-x, -y).

A lever can rotate around the fixed point that is called a pivot. Levers are used to reduce the force need to do a particular task.
