How do you find the coordinates of a figure when it is rotated 180 degrees around the origin?

Think of any figure, with any shape, on the graph with the origin inside the shape.
Now think of any point inside the shape (except the origin).
Now, in your imagination, slowly and carefully turn the shape 180 degrees around the origin ...
as if it were stuck to the origin with a pin, and you gave it 1/2 turn on the pin.
What happened to the point you were thinking of ?
If the point started out some distance to the right of the y-axis, it wound up the same distance
to the left of the y-axis.
And if it started out some distance above the x-axis, it wound up the same distance below the x-axis.
So ... any point that starts out at the coordinates ( x , y ) before the 1/2 turn, winds up
at the coordinates ( -x , -y ) after the 1/2 turn.

How do you rotate a figure 180 degrees clockwise about origin?
To rotate a figure 180 degrees clockwise about the origin you need to take all of the coordinates of the figure and change the sign of the x-coordinates to the opposite sign(positive to negative or negative to positive). You then do the same with the y-coordinates and plot the resulting coordinates to get your rotated figure.
What kind of figure can be rotated less than 360 degrees around the center point and coincide with the original figure?
If it's an *equilateral* triangle, a triangle. Check out quadrilaterals (squares, rectangles), then *equilateral* pentagons, hexagons, etc. Generally, an equilateral polygon needs only rotate (360/number of sides) degrees to coincide.
How would you find the vertices of an image of a figure were rotated 270 degrees clockwise?
The image of a vertex at (x, y) would be (-y, x).

How do you rotate a figure 180 degrees clockwise?

How do you rotate a figure 180 degrees about origin?
Visualize a capital "N." Rotated 90 degrees counter-clockwise (a quarter turn to the left) it would look like a capital "Z."
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).
