How do you know that a figure does not have rotational symmetry?
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
How do you rotate a figure on a graph 180 degrees?
If a point is at coordinates (x , y), then move it to (-x, -y).
A figure that turns around a fixed point?
lilo
A movement of a figure to a new position by rotating the figure around a point?
ordered pair
How do you reflect a figure around the origin?
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.
How do you find the smallest angle of rotational symmetry for a figure?
If you can rotate (or turn) a figure around a center point by fewer than 360° and the figure appears unchanged, then the figure has rotation symmetry. The point around which you rotate is called the center of rotation, and the smallest angle you need to turn is called the angle of rotation. This figure has rotation symmetry of 72°, and the center of rotation is the center of the figure:
To turn around a center point?
To turn around a centre point is to rotate.
How do you rotate a figure 90 degrees counter clockwise then reflect over y axis?
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 transformation in which a figure is turned around a point?
Its called points maybe
How do you rotate a triangle around a point?
turn it from the middle
How do you rotate a figure on a graph 180 degrees?
If a point is at coordinates (x , y), then move it to (-x, -y).
What is the function of the lever?
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.
What are epicycles?
an epicycle is a system where things rotate around a fixed point.
What does a lever need to be a lever?
needs to have a fixed point that it can rotate around
After Joaquin draws a figure on a computer screen, he decides to rotate the figure counterclockwise through an angle of 180°.What is the image of the point (-4, 3)?
4, -3
What is the earths center of gravity?
Its a theoretical point, if you threw it in the air spinning, it would rotate around this point.
