What us the order of rotational symmetry of letter H?
The letter H has a rotational symmetry of order 2, meaning it looks the same after a 180-degree rotation.
What is the degree of longitude of the IDL?
180
What is the difference between the international date line and a time zone?
180 degree meridian is the meridiam ospposite to the Prime Meridean or The Greenwich Meridian. It helps to find the location of a place. The 180 degree west and the 180 degree east are the same meridians. Whereas, the International Date Line or the IDL is an imaginary line that runs ALONG the 180 degree meridian. It bend slightly to avoid land. If a person travells eastward of it , he /she gains a day, but if a person travells westward of it he/she loses a day.
What is the rotational symmetry of the letter U?
The letter U has rotational symmetry of order 1 because it looks the same after a 180-degree rotation.
What type of angle is a 120 degree angle?
A 120 degree angle is an obtuse angle. This means that the angle is between 90 and 180 degrees.
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.
What degree clockwise rotation goes from xy to -xy?
180 degrees in the plane perpendicular to the xy plane. In general, no rotation in the (x, y) plane will take it to (-x, y) unless x = y (or -y) and, in that case it is a 270 degree clockwise rotation.
Why doesn't the direction of rotation clockwise and counterclockwise matter when the angle of rotation is 180?
Because 180 degrees clockwise is the same as 180 degrees counterclockwise.
What is the rule for a 180 degree counterclockwise rotation?
First of all, if the rotation is 180 degrees then there is no difference clockwise and anti-clockwise so the inclusion of clockwise in the question is redundant. In terms of the coordinate plane, the signs of all coordinates are switched: from + to - and from - to +. So (2, 3) becomes (-2, -3), (-2, 3) becomes (2, -3), (2, -3) becomes (-2, 3) and (-2, -3) becomes (2, 3).
What is the image of (1 -6) for a 180 counterclockwise rotation about the origin?
It is (-1, 6).Also, if the rotation is 180 degrees, then clockwise or anticlockwise are irrelevant.It is (-1, 6).
180 degrees counterclockwise rotation?
Fomula(work with both clockwise/counterclockwise):(-x,-y)
What is the degree for a half of rotation?
180 degrees
What is the value of a 1971 Kennedy half dollar with a 180 degree rotation?
A 180 degree rotation between front and back is normal for US coins.
what is the image of the point (-2,7) after a rotation of 180 counterclockwise about the origin?
The rule for a rotation by 180° about the origin is (x,y)→(−x,−y) .
How do you do 180 degree rotation of a shape on a coordinate?
(-e, -h)
(2,3) after rotation of 180 counter clockwise?
our point A(x,y) becomes A'(-x,-y).
What fraction is equivalent to a 180 degree turn?
180 degrees is half a rotation so probably a half.
