Exploring Geometric Rotations

This video tutorial covers the concept of rotating figures on a coordinate plane. It explains the properties of each quadrant and how rotations affect the position and orientation of shapes. The tutorial provides step-by-step instructions for performing 90-degree clockwise and counterclockwise rotations, as well as 180-degree and 270-degree rotations. It emphasizes that rotations are rigid transformations, meaning the size and shape of the figure remain unchanged, only its position and orientation are altered.

What is the result of rotating a point from quadrant one to quadrant two?

• 270-degree clockwise rotation

• 180-degree rotation

• 90-degree counterclockwise rotation

• 90-degree clockwise rotation

What is the effect of a 90-degree counterclockwise rotation from quadrant two to quadrant three?

• Coordinates are swapped and signs change

• No change to coordinates or signs

• Coordinates are swapped but signs remain the same

• Only the signs of the coordinates change

After a 90-degree rotation, how are the new coordinates determined from the original?

• Swap x and y, signs remain the same

• Swap x and y, then change signs

• No change to coordinates

• Only x becomes y, y becomes x
