Math Problem Statement

Triangle T has been rotated clockwise/anticlockwise by ___° about the point (___,___) to give triangle U. Determine the details of the transformation.

Solution

The image shows a transformation problem where triangle T is rotated to give triangle U.

Details:

  • Rotation Type: The image suggests that triangle T is rotated clockwise to get triangle U.
  • Angle: The transformation appears to be a 90° clockwise rotation.
  • Point of Rotation: The red "X" marks the origin (0, 0) as the center of rotation.

Thus, the full transformation would be described as:

  • Rotation Type: Clockwise
  • Angle: 90°
  • Center of Rotation: (0, 0)

Would you like a detailed explanation of how I determined the transformation, or do you have any other questions?

Here are 5 relative questions to expand your understanding:

  1. How does a 90° clockwise rotation affect the coordinates of a point?
  2. What changes would occur if the rotation was counterclockwise instead?
  3. How can you determine the center of rotation from the coordinates of the triangles?
  4. What would happen if the rotation angle was 180° instead of 90°?
  5. How can we check the rotation transformation using matrices?

Tip: When rotating objects, remember that clockwise and counterclockwise rotations have opposite effects on the position of the object.
