Activity 3: Rotation.

What is the angle of rotation when a shape makes quarter turn?

• 270 degrees

• 360 degrees

• 90 degrees

• 180 degrees

If a point is rotated 180 degrees counterclockwise around the origin, what are the new coordinates?

• The new coordinates are (y, x)

• The new coordinates are (-x, -y)

• The new coordinates are (x, -y)

• The new coordinates are (x, y)

Which direction does a clockwise rotation follow?

• Down

• Left

• Right

• Up

In mapping notation, what does (x, y) -> (-y, x) represent?

• (-y, -x)

• 90-degree clockwise rotation

• (-x, -y)

• 90-degree counterclockwise rotation

After a 90 degrees counterclockwise rotation around origin, what are the new coordinates of the point (2, -3)?

• (-2, 3)

• (3, 2)

• (-3, -2)

• (2, 3)

What is the result of a 180 degrees clockwise rotation of a rectangle?

• Circle

• Rectangle

• Square

• Triangle

What are the coordinates after a 180 degrees clockwise rotation around origin of the point (4, 5)?

• (4, -5)

• (5, -4)

• (-5, 4)

• (-4, -5)

What does a 360 degrees rotation of a shape result in?

• The shape splits into two.

• The shape shrinks in size.

• The shape disappears.

• The shape returns to its original position.

After a 90 degrees clockwise rotation around origin, what are the new coordinates of the point (-6, -2)?

• (6, -2)

• (-2, 6)

• (2, -6)

• (-6, 2)

What are the coordinates after a 180 degrees counterclockwise rotation of the point (-3, 4)?

• (-4, 3)

• (3, 4)

• (4, -3)

• (3, -4)
