What is it called when you rotate a figure around a point?
A rotation
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 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).

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.
How do you you rotate a figure 90 degrees clockwise about the origin?
To rotate a figure 90 degrees clockwise about the origin, simply swap the x and y coordinates of each point and then negate the new y-coordinate. This is equivalent to reflecting the figure over the line y = x and then over the y-axis.

How do you rotate a figure 180 degrees counterclockwise around the origin?
For every point A = (x,y) in your figure, a 180 degree counterclockwise rotation about the origin will result in a point A' = (x', y') where: x' = x * cos(180) - y * sin(180) y' = x * sin(180) + y * cos(180) Happy-fun time fact: This is equivalent to using a rotation matrix from Linear Algebra! Because a rotation is an isometry, you only have to rotate each vertex of a polygon, and then connect the respective rotated vertices to get the rotated polygon. You can rotate a closed curve as well, but you must figure out a way to rotate the infinite number of points in the curve. We are able to do this with straight lines above due to the property of isometries, which preserves distances between points.
To turn around a center point?
To turn around a centre point is to rotate.
How do you find the smallest angle of rotational symmetry for a figure?
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.
How do you rotate a triangle around a point?
turn it from the middle
What was the point and date of origin of Hinduism?
Nobody knows. If you figure it out then you will be world famous.
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).
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
