How can you tell the quadrant in which a point is located without refferring to the graph?
If the signs of the Cartesian coordinates are: (+, +) => first quadrant (-, +) => second quadrant (-, -) => third quadrant (+, -) => fourth quadrant. If one of the coordinates is 0 then the point is on an axis and NOT in a quadrant. If both coordinates are 0 then the point is at the origin. If the location of the point is given in polar coordinates, then you only need the angle. Suppose the principal angle is Φ, then 0 < Φ < 90 degrees => first quadrant 90 < Φ < 180 => second quadrant 180 < Φ < 270 => third quadrant 270 < Φ < 360 => fourth quadrant. Again, if the angle is 90, 180 etc degrees, the point is on an axis. If the magnitude is 0 then the point is at the origin.
Does a triangle have point symmetry?
No, a triangle does not have point symmetry. Point symmetry occurs when an object or shape remains the same after being rotated 180 degrees around a central point. In the case of a triangle, it does not have point symmetry because it does not look the same after a 180-degree rotation.
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).
If a pair of parallel lines are rotated which is true?
THE LINE REMAINS PARELL ONLY IF ROTATED IN 180
How many degrees must a rectangle be rotated in order to map onto itself?
It will be 180 degrees
What are the coordinates of the image of the point 2 5 after it is rotated 180 degrees clockwise about the origin?
Rotating it about the origin 180° (either way, it's half a turn) will transform a point with coordinates (x, y) to that with coordinates (-x, -y) Thus (2, 5) → (-2, -5)
Point Q was rotated about origin (0,0) by 180 degrees?

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 is true about corresponding line segments of an object that has been rotated 180 degrees about the origin?
The line segments will have been rotated by 180 degrees.
Point Q was rotated about the origin (0,0) by 180 degrees?
depending on the graph where point Q was you would not be able to tell where point Q ended after the rotaion finshed
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 distanceto 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 upat the coordinates ( -x , -y ) after the 1/2 turn.
What is the image of point (3 5) if the rotation is-180?
If the point (3,5) is rotated 180 degrees, it becomes (-3,-5).

How many degrees has triangle ABC been rotated counterclockwise about the origin?
180 degrees.
What is the image of point (3 5) if the rotation is 180º?
If the point (3,5) is rotated 180 degrees, it becomes (-3,-5).
What is the image of 1 -6 after a 180 degree counterclockwise rotation about the origin?
A 180° rotation is half a rotation and it doesn't matter if it is clockwise of counter clockwise. When rotating 180° about the origin, the x-coordinate and y-coordinates change sign Thus (1, -6) → (-1, 6) after rotating 180° around the origin.
