Because (3,4) is in quadrant I and will end up in quadrant IV with a 90º clockwise rotation, the x-value must be positive and the y-value negative.
How do you rotate a point 90 degrees clockwise about a point?
Answer: To rotate the figure 90 degrees clockwise about a point, every point(x,y) will rotate to (y, -x).
What is the rule after a 90 degree clockwise rotation?
Rule : When we rotate a figure of 90 degrees clockwise, each point of the given figure has to be changed from (x, y) to (y, -x) and graph the rotated figure.
What are the rules for 90 degrees clockwise and counterclockwise?
Here are the rotation rules: 90° clockwise rotation: (x,y) becomes (y,-x) 90° counterclockwise rotation: (x,y) becomes (y,x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
What is 90 degrees counterclockwise?
When we rotate a figure of 90 degrees counterclockwise, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure. Example 1 : If this triangle is rotated 90° counterclockwise, find the vertices of the rotated figure and graph. …
What is 90 degrees in an angle?
right angle-an 90 degree angle. obtuse angle-an angle between 90 and 180 degrees. straight angle-a 180 degree angle.
What are the coordinates of the figure after a 90 clockwise rotation about the origin?
When the point is rotated through 90° clockwise about the origin, the point M (h, k) takes the image M’ (k, -h). Therefore, the new position of point M (-2, 3) will become M’ (3, 2). 2. Find the co-ordinates of the points obtained on rotating the point given below through 90° about the origin in clockwise direction.
