Now imagine rotating the entire 4th quadrant one-quarter turn in a clockwise direction: Note the location of Point D’, the image of Point D after a -90-degree rotation. Since the rotation is 90 degrees, you will rotating the point in a clockwise direction. This example should help you to visually understand the concept of counterclockwise geometry rotations.Ĭan you rotate the 4th quadrant in a clockwise direction? When to rotate point c 180 or counterclockwise?Īnd this process could be repeated if you wanted to rotation Point C 180 degrees or 270 degrees counterclockwise: Point C after a 180-degree rotation. If you represent the point ( x, y) in the plane as a complex number x + i y, then multiplying it by i rotates it 90 ∘ counterclockwise and multiplying it by − i rotates it 90 ∘ clockwise. How to rotate a point through a 90 degree plane?īTW: To rotate clockwise, replace ( x, y) with ( y, − x). Let us look at some examples to understand how 90 degree clockwise rotation can be done on a figure. 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. 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’s the rule for 90 degree clockwise rotation? What are the rules for 90 degrees clockwise and counterclockwise? Triangle B is rotated 90° counterclockwise with the origin as the center of rotation to create a new figure. Which triangle shows a 90 degree counterclockwise rotation? Is 90 degrees clockwise or counterclockwise? Find the co-ordinates of the points obtained on rotating the point given below through 90° about the origin in clockwise direction. Therefore, the new position of point M (-2, 3) will become M’ (3, 2). When the point is rotated through 90° clockwise about the origin, the point M (h, k) takes the image M’ (k, -h). What is the rule for rotating 90 degrees clockwise about the origin? 4 When to rotate point c 180 or counterclockwise?.3 What’s the rule for 90 degree clockwise rotation?.2 Which triangle shows a 90 degree counterclockwise rotation?.1 What is the rule for rotating 90 degrees clockwise about the origin?.
