![]() In many cases, a translation will be both horizontal and vertical, resulting in a diagonal slide across the coordinate plane. Negative values equal vertical translations downward. Positive values equal vertical translations upward. Negative values equal horizontal translations from right to left.Ī vertical translation refers to a slide up or down along the y-axis (the vertical access). As youll see, the student must revise their definition several times to make it more and more precise. Their goal is to describe rotations in general using precise mathematical language. ![]() The dialog below is between a teacher and a student. Positive values equal horizontal translations from left to right. Read a dialog where a student and a teacher work towards defining rotations as precisely as possible. Vertical TranslationsĪ horizontal translation refers to a slide from left to right or vice versa along the x-axis (the horizontal access).

In case, there is an object which is rotating that can rotate in different ways as shown below:ģ.A translation is a slide from one location to another, without any change in size or orientation. You can see the rotation in two ways ie., clockwise or counterclockwise. Is a 90 Degree rotation clockwise or counterclockwise?Ĭonsidering that the rotation is 90 Degree, you should rotate the point in a clockwise direction. I believe that the above graph clears all your doubts regarding the 90 degrees rotation about the origin in a clockwise direction. The rule/formula for 90 degree clockwise rotation is (x, y) -> (y, -x).Īfter applying this rule for all coordinates, it changes into new coordinates and the result is as follows: ![]() Next, find the new position of the points of the rotated figure by using the rule in step 1.įinally, the Vertices of the rotated figure are P'(3, 6), Q’ (6, -9), R'(7, -2), S'(8, -3).įind the new position of the given coordinates A(-5,6), B(3,7), and C(2,1) after rotating 90 degrees clockwise about the origin? In step 1, we have to apply the rule of 90 Degree Clockwise Rotation about the Origin Now, we will solve this closed figure when it rotates in a 90° clockwise direction, If this figure is rotated 90° about the origin in a clockwise direction, find the vertices of the rotated figure. Let P (-6, 3), Q (9, 6), R (2, 7) S (3, 8) be the vertices of a closed figure. (iii) The current position of point C (-2, 8) will change into C’ (8, 2) (ii) The current position of point B (-8, -9) will change into B’ (-9, 8) (i) The current position of point A (4, 7) will change into A’ (7, -4) When the point rotated through 90º about the origin in the clockwise direction, then the new place of the above coordinates are as follows: Solve the given coordinates of the points obtained on rotating the point through a 90° clockwise direction?
