Exploring Rigid Motions: Rotation A

This video tutorial explains how to rotate figures using paddy paper. It covers the setup process, including tracing the figure and center point, and emphasizes the importance of positive, counterclockwise rotations. The tutorial demonstrates the rotation process using a pencil to hold the paddy paper in place and discusses potential human errors in the final result.

What tool is used to rotate figures in the video?

• Protractor

• Compass

• Ruler

• Paddy paper

What is the significance of D being greater than zero?

• It means the rotation is clockwise.

• It means the rotation is counterclockwise.

• It means the rotation is exactly 180 degrees.

• It means the rotation is exactly 90 degrees.

In which direction do positive rotations move?

• Clockwise

• Counterclockwise

• Upwards

• Downwards

What should be traced on the paddy paper before rotating?

• Only the point

• Both the figure and the point

• Neither the figure nor the point

• Only the figure

What is the main goal when tracing the figure and point on the paddy paper?

• To make it smaller

• To make it colorful

• To make it as accurate as possible

• To make it larger

What is the key requirement for the degree of rotation?

• It must be a negative value.

• It must be a positive value.

• It must be exactly 90 degrees.

• It must be exactly 180 degrees.

How should the pencil be used during the rotation?

• To draw a new figure

• To hold down the paddy paper

• To erase the original figure

• To measure the angle

What should you do after rotating the paddy paper to the desired angle?

• Remove the paddy paper

• Trace the new position of the figure

• Erase the original figure

• Color the new figure

What might cause the rotated figure to not be perfect?

• Bad lighting

• Incorrect angle

• Human error

• Wrong tool

What is the final step after rotating the figure?

• Label the rotated figure

• Erase the original figure

• Color the rotated figure

• Measure the new angles
