• Sliding or moving

What is the key concept of rotation?

• Moving along a vector

• Enlarging or reducing the object

What is the angle measurement when rotating 360 degrees?

• 270 degrees

• 180 degrees

• 360 degrees

• 450 degrees

What property of rotation ensures that line segment lengths are maintained?

• Line segment lengths are preserved

• Angle measurements are preserved

• Line segments map to line segments

• Object stays closer when point of rotation is closer

What is the difference in length between segment AV and segment A'V' after rotating 60 degrees?

• They are the same size

• AV is longer than A'V'

• A'V' is longer than AV
