Learn how to rotate a triangle 90 degrees clockwise about the origin

The video tutorial explains how to rotate a figure 90 degrees clockwise using both manual and algebraic methods. It begins with a manual approach using paper to visualize the rotation, followed by an algebraic method that involves swapping and negating coordinates. The tutorial also covers plotting the new coordinates and compares clockwise and counterclockwise rotations.

What is one challenge mentioned when using paper to manually rotate a figure?

• Finding the exact coordinates

• Understanding the concept of rotation

• Identifying the x-axis

• Drawing the figure accurately

What is the algebraic rule for rotating a point 90 degrees clockwise?

• Swap x and y, negate the y-coordinate

• Swap x and y, negate the x-coordinate

• Negate both x and y coordinates

• Double the x-coordinate, halve the y-coordinate

After applying the rotation rule, what is the new position of point A if its original coordinates are (3, -6)?

• (-6, 3)

• (6, -3)

• (3, 6)

• (-3, -6)

What is the equivalent counterclockwise rotation for a 90-degree clockwise rotation?

• 270 degrees counterclockwise

• 360 degrees counterclockwise

• 180 degrees counterclockwise

• 90 degrees counterclockwise

What is the new position of point C if its original coordinates are (4, 0) after a 90-degree clockwise rotation?

• (4, 0)

• (0, 4)

• (-4, 0)

• (0, -4)
