How do you rotate a shape around the origin?

Usually, you will be asked to rotate a shape around the origin, which is the point (0, 0) on a coordinate plane. You can rotate shapes 90, 180, or 270 degrees around the origin using three basic formulas. Note the corresponding clockwise and counterclockwise rotations. Rotating a shape 90 degrees is the same as rotating it 270 degrees clockwise.

How do you rotate a point by 60 degrees?

This is point P. Its being rotated around the origin (0,0) by 60 degrees. So if originally point P is right over here and were rotating by positive 60 degrees, so that means we go counter clockwise by 60 degrees. So this looks like about 60 degrees right over here.

What is an example of counterclockwise rotation?

For example, if the problem states, “Rotate the shape 90 degrees around the origin,” you can assume you are rotating the shape counterclockwise. You would complete this problem the same way you complete a problem that asks “Rotate the shape 270 degrees clockwise around the origin.”

How do I use a rotation tester?

A rotation tester can be connected to three phase motor and supply leads in order to determine the how a motor will rotate once power is applied. Disconnect power to the motor and lockout/tag-out as required. Plug the three test leads into the rotation tester. Attached the alligator clips to the corresponding motor leads.

How to rotate a shape about the origin 90° counter-clockwise?

How to Rotate a Shape About the Origin 90° Counter-Clockwise? Step 1: Find the points of the vertices. Step 2: Switch the x and y values for each point. Step 3: Multiply the new x-values by -1. Show Step-by-step Solutions

How to rotate a shape 180 degrees?

If you want to rotate a shape 180 degrees around the point of origin, turn the x and y coordinates into -y and -x coordinates. So, if a line has the coordinates 2,4 and 4,5, it would rotate to -4,-2 and -5,-4. Read more to learn how to rotate a shape 270 degrees!

How to rotate a polygon around the origin?

Rotating a polygon around the origin. For a 90 degree rotation around the origin, switch the x,y values of each ordered pair for the location of the new point. If playback doesnt begin shortly, try restarting your device. Videos you watch may be added to the TVs watch history and influence TV recommendations.

What direction do you rotate a shape on a coordinate plane?

Conventionally, shapes are rotated counterclockwise on a coordinate plane. You should assume this, unless it is noted in the problem that you need to rotate clockwise. For example, if the problem states, “Rotate the shape 270 degrees around the origin,” you can assume you are rotating the shape counterclockwise.

How do you test a 3 phase rotation tester?

A rotation tester can be connected to three phase motor and supply leads in order to determine the how a motor will rotate once power is applied. Disconnect power to the motor and lockout/tag-out as required. Plug the three test leads into the rotation tester.

Why test the rotation of your equipment?

Regardless of the application, it’s a good practice to always test rotation and reduce the risk of damaging equipment. So you just spent three hours removing and replacing a motor that drives the feed to a robotic welder.

How do you test the direction of rotation of a shaft?

The tester will display either clockwise or counterclockwise rotation. If the tester shows counterclockwise rotation while turning the shaft clockwise, swap and two of the leads and repeat the test until the tester indicates the correct rotation direction. Label motor leads A, B, C.

What if I do not have a phase rotation test?

If you do not have access to a phase rotation tester then a motor bump test can be performed instead. A rotation tester can be connected to three phase motor and supply leads in order to determine the how a motor will rotate once power is applied.
