Math Problem Statement

What is the image of F(-2, 7) after a rotation of 180° clockwise?

Solution

The problem asks for the image of the point F(2,7)F(-2, 7) after a 180° clockwise rotation.

To solve this, we can use the formula for rotating a point 180° around the origin. For any point (x,y)(x, y), a 180° rotation will map it to (x,y)(-x, -y).

Steps:

  • The original point is F(2,7)F(-2, 7).
  • After a 180° clockwise (or counterclockwise, since they are the same for 180°) rotation, the coordinates of the new point will be: F((2),(7))=F(2,7)F'(-(-2), -(7)) = F'(2, -7)

So, the image of F(2,7)F(-2, 7) after a 180° rotation is F(2,7)F'(2, -7).

The correct answer is F'(2, -7) (the orange option).

Here are 5 related questions to expand on this:

  1. How do you perform a 90° clockwise rotation of a point?
  2. What would be the image of (2,7)(2, -7) after a 270° clockwise rotation?
  3. How does a 180° rotation differ from a reflection over the origin?
  4. How do rotations affect the orientation of a shape or object?
  5. Can you explain the general rule for rotating a point by any angle?

Tip: A 180° rotation always maps a point to its opposite quadrant while flipping the signs of both coordinates.
