What is negative bearing?
a bearing is the angle from north moving clockwise 360 degrees a negative bearing is moving counterclockwise from north
What is the reference angle for -490 degrees?
When using autocad, 0 degrees was at 3 o' clock, then go anticlockwise for positive, clockwise for negative
If an angle measures over 90 degrees what is its complement?
obtuse angle * * * * * The complement of an angle greater than 90 degrees is not an obtuse angle! It would be a negative angle, whose measure would be 90 minus the angle whose complement you require. This would only make sense if the direction in which the angles were measured were fixed. For example bearings, which are always measured in the clockwise direction.
What is a rotation of symmetry?
Sometimes called rotation symmetry, or symmetry of rotation. If you have an object that can be turned through a certain angle (like rotating a cube through 90o) and then it looks identical, then that object has a certain symmetry under rotation. If you can turn it through any angle, like a cylinder, then it has rotation (or rotational) symmetry.
How do you find the complement of a negative angle?
To find the complement of a negative angle, you first need to determine its positive equivalent by adding 360 degrees to the negative angle. Once you have the positive angle, you can then find its complement by subtracting the angle from 90 degrees. This will give you the complement of the negative angle in the range of 0 to 90 degrees.
