Understanding 180-Degree Rotations

The video tutorial explains how to rotate a figure 180 degrees, both clockwise and counterclockwise, by negating the x and y coordinates. It demonstrates plotting the new points and connecting them to form the rotated figure. The tutorial emphasizes that the direction of rotation does not matter for 180 degrees, and verifies the process using a sheet of paper.

What is the result of rotating a figure 90 degrees twice?

• A 270-degree rotation

• A 360-degree rotation

• A 180-degree rotation

• A 90-degree rotation

How do you achieve a 180-degree counterclockwise rotation using coordinates?

• Switch and negate the coordinates

• Negate both x and y coordinates

• Negate the x-coordinate only

• Switch the x and y coordinates

What should be negated to perform a 180-degree rotation?

• Only the x-coordinate

• Only the y-coordinate

• Neither coordinate

• Both x and y coordinates

What is the new coordinate of point L after a 180-degree rotation if it was originally (1, 1)?

• (-1, -1)

• (-1, 1)

• (1, 1)

• (1, -1)

After plotting the rotated points, what is the next step to complete the rotation process?

• Erase the original figure

• Connect the plotted points

• Switch the coordinates again

• Rotate the figure 90 degrees more

What tool is used to verify the rotation process in the video?

• A compass

• A ruler

• A sheet of paper

• A protractor

What is confirmed by using a sheet of paper in the rotation process?

• The original position of the figure

• The appearance of the rotated figure

• The size of the figure

• The color of the figure

What is the final step in confirming a 180-degree rotation?

• Re-rotating the figure

• Using a sheet of paper

• Checking the original figure

• Measuring the angles

Does the direction of a 180-degree rotation affect the final position of the figure?

• Yes, but only for clockwise rotations

• Yes, but only for counterclockwise rotations

• No, it remains the same

• Yes, it changes the position

What is the key point to remember about 180-degree rotations?

• They require a specific direction

• They are the same regardless of direction

• They are only possible clockwise

• They are only possible counterclockwise
