![]() Here is the next degree rotation on our list that we have explained for you. Example 1 : Let F (-4, -2), G (-2, -2) and H (-3, 1) be the three vertices of a triangle. Please enter another rotation in degrees for us to illustrate and explain. 90 DEGREE COUNTERCLOCKWISE ROTATION RULE 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. Therefore, the hour hand on a clock, indicated by the blue line, is at 3:00 because 180 minutes You may also be interested to know that the area covered by traveling from 0 to 90 degrees on a circle constitutes 25 percent of the circle,įurthermore, there are 720 minutes on a clock, and 25 percent of 720 is 180 minutes. Out of 360 degrees, we get our end line of 90 degrees, which is marked by a blue line. If you look at our illustration, you can see that we start at 0 degrees (or 12 o'clock) marked by a red line. Furthermore, clockwise means that you circle in the right direction (same direction as the hands on an analog clock). 90 degree rotation means that we want to travel 90 degrees One complete rotation around a circle is 360 degrees. We will start by displaying theĩ0 degree clockwise rotation illustration and then explain its parts. The are the same thing and you will use the same formula. How to rotate a figure 90 degrees clockwise about a point Get the answer to this question and access a vast question bank that is tailored for students. It does not store any personal data.Read this page to find out what a 90 degree clockwise rotation means on a circle (or clock). There is no difference between 90-degree Clockwise Rotation and 270-degree counter clockwise rotation.

Before Rotation (x, y) After Rotation (y, -x) Example 1 : Let K (-4, -4), L (0, -4), M (0, -2) and N (-4, -2) be the vertices of a rectangle. The curves show how each corner moves as it is rotated. 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. ![]() The following diagram shows the original rectangle A B C D and the rotated rectangle A B C D. Draw the original rectangle and its position after being rotated. The cookie is used to store the user consent for the cookies in the category "Performance". The rectangle is to be rotated through 90 ° clockwise about the origin. This cookie is set by GDPR Cookie Consent plugin.

You have to rotate the image in-place, which means you have to modify the input 2D matrix directly. ![]()
