The original point of (2, 3) and the Image Point will always be equidistant from the Mirror Line over which the original point is reflected. 90 DEGREE CLOCKWISE ROTATION 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. Line Y = X is the Line that passes through the origin and creates a 45 degree angle with the X axis So the first rotation gives us point (2, 3) Or, the explanation is too long winded, you can follow the Rule:įor 90 degree rotations clockwise about the Origin: (X, Y) ->becomes image point of (Y, -X) These 2 points and the origin will create a 90 degree angle about the Origin (both lines are diagonals of their respective rectangles) and connecting new image point A at (2, 3) Learn vocabulary, terms, and more with flashcards, games, and other study tools. connecting original point A at (-3 ,2) with the Origin Start studying Rules for Rotating 90 and 180 Degrees. Point A would now move to the upper right corner of this new rectangle that we pushed over -> this will be point (2, 3) This would give us a rectangle of 2 units along the positive X axis and 3 units along positive Y axis. Now imagine lifting the rectangle up and pushing it from quadrant 2 into quadrant 1 - i.e, a 90 degree rotation clockwise about the Origin If we join the horizontal and vertical lines to the Y and X axis, respectively, we end up with a rectangle that is 3 units along the Negative X Axis and 2 units along the Positive Y Axis Label (-3, 2) as point A and Origin as Point O We receive this nice of 270 Clockwise Rotation graphic could possibly be the most trending subject following we ration it in google gain or facebook. Its submitted by management in the best field. We identified it from trustworthy source. Since we are rotating 90 degrees about the Origin (0, 0) -> make a rectangle with these 2 points Here are a number of highest rated 270 Clockwise Rotation pictures on internet. When plot these points on the graph paper, we will get the figure of the image (rotated figure).The way I understood 90 degree rotations was by the “tipping the rectangle” method. In the above problem, vertices of the image areħ. When we apply the formula, we will get the following vertices of the image (rotated figure).Ħ. When we rotate the given figure about 90° clock wise, we have to apply the formulaĥ. When we plot these points on a graph paper, we will get the figure of the pre-image (original figure).Ĥ. In the above problem, the vertices of the pre-image areģ. To write a rule for this rotation you would write: R270 (x,y)(y,x). Therefore the Image A has been rotated 90 to form Image B. First we have to plot the vertices of the pre-image.Ģ. Notice that the angle measure is 90 and the direction is clockwise.
#90 CLOCKWISE ROTATION RULE HOW TO#
So the rule that we have to apply here is (x, y) -> (y, -x).īased on the rule given in step 1, we have to find the vertices of the reflected triangle A'B'C'.Ī'(1, 2), B(4, -2) and C'(2, -4) How to sketch the rotated figure?ġ. Here triangle is rotated about 90 ° clock wise. If this triangle is rotated about 90 ° clockwise, what will be the new vertices A', B' and C'?įirst we have to know the correct rule that we have to apply in this problem. Let A(-2, 1), B (2, 4) and C (4, 2) be the three vertices of a triangle. Let us consider the following example to have better understanding of reflection.

Here the rule we have applied is (x, y) -> (y, -x). Once students understand the rules which they have to apply for rotation transformation, they can easily make rotation transformation of a figure.įor example, if we are going to make rotation transformation of the point (5, 3) about 90 ° (clock wise rotation), after transformation, the point would be (3, -5).
