How do you rotate a figure 90 degrees counterclockwise about origin?
Ex: -1,-2 Switch the numbers, so with the example it would be -2,-1. Next multiply your x coordinate by -1,so the example would be 2,-1
How do you rotate 270 degrees about origin?
You rotate everything to the left, 3/4 of a full turn.As an example of the result, the positive x-axis winds uppointing down from the origin.
How do you rotate a triangle 90 degrees counterclockwise?
Rotating a triangle 90 degrees counterclockwise would involve taking an upright triangle and laying is toward the left on its back. Changing position through rotation can cause a better visualization for some problem solving.
What is the smallest angle through which you can rotate a regular hexagon onto itself?
60 degrees. You find this by taking 360 and dividing by the total sides (6) which leaves you with the degrees of the exterior angles, this exterior angle is how little you can rotate any polygon for that matter.
How do you rotate a figure 90 degrees counterclockwise about the origin?
Given a set of points, (x1, y1), (x2, y2), etc. Take the absolute value of each point's x and y values, and replace those. Take the inverse point of each point, e.x. (x1, y1) -> (y1, x1) Apply the signs that correspond to the quadrant counterclockwise of the quadrant the point was in. e.x. (3, 5) is in the First Quadrant. The Second Quadrant is counterclockwise of the First, so we will have the x-value of the point negative: (-3, 5). Do that for all points.
How do you rotate 180 degrees counter clockwise about origin?
To rotate a point 180 degrees counterclockwise about the origin, you can simply change the signs of both the x and y coordinates of the point. For example, if the original point is (x, y), after the rotation, the new coordinates will be (-x, -y). This effectively reflects the point across the origin.
Suppose a figure is located in quadrant 1. Which of the following will result in an image that is located in quadrant 3?
A) Rotate 360 degrees counterclockwise, then shift 1 unit up. B) Rotate 180 degrees counterclockwise, then shift 1 unit down. C)Rotate 90 degrees counterclockwise, then shift 1 unit up. D) Rotate 270 degrees counterclockwise, then shift 1 unit down.
What is the answer to rotate 180 degrees counterclockwise?
The same as 180 degrees clockwise. What do you mean "the answer to"?
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.
Can you rotate text counterclockwise by entering a number between 1 degrees and 180 degrees on the alignment sheet?
True
How do you rotate selected cells 45 degrees counterclockwise?
To rotate selected cells 45 degrees counterclockwise in Excel, first select the cells you want to rotate. Then, right-click and choose "Format Cells." In the Format Cells dialog, go to the "Alignment" tab, and use the "Orientation" section to set the text rotation to 45 degrees. Click "OK" to apply the changes.
How do you rotate a figure 270 degrees clockwise about origin?
You dont, its just 90 degrees 3 times..
How do you rotate a figure 90 degrees counterclockwise about origin?

Do most tornadoes in the northern hemisphere rotate in a clockwise or a counterclockwise direction?
Most tornadoes in the northern hemisphere, at least 99%, rotate counterclockwise.
How do you rotate 270 degrees about origin?
You rotate everything to the left, 3/4 of a full turn.As an example of the result, the positive x-axis winds uppointing down from the origin.
Do tornadoes rotate counterclockwise?
Most tornadoes (about 99%) in the northern hemisphere rotate counterclockwise. But most in the southern hemisphere rotate clockwise.
