quadrilateral WVUT undergoes a counterclockwise rotation of 90 degrees.

W(-4,1), V(-5,-4), U(-3,0), and T(0,-1)
What are the coordinates of the image W'V'U'T'?

1 answer

To find the coordinates of the image of quadrilateral WVUT after a counterclockwise rotation of 90 degrees, we will apply the rotation transformation to each vertex.

The general rule for rotating a point \((x, y)\) counterclockwise by 90 degrees about the origin is: \[ (x, y) \to (-y, x) \]

Now we will apply this transformation to each vertex:

  1. Point W: \[ W(-4, 1) \to W'(-1, -4) \]

  2. Point V: \[ V(-5, -4) \to V'(4, -5) \]

  3. Point U: \[ U(-3, 0) \to U'(0, -3) \]

  4. Point T: \[ T(0, -1) \to T'(1, 0) \]

Now, let's summarize the new coordinates of the vertices \(W', V', U', T'\):

  • \(W'(-1, -4)\)
  • \(V'(4, -5)\)
  • \(U'(0, -3)\)
  • \(T'(1, 0)\)

Thus, the coordinates of the image \(W'V'U'T'\) after a counterclockwise rotation of 90 degrees are:

  • \(W'(-1, -4)\)
  • \(V'(4, -5)\)
  • \(U'(0, -3)\)
  • \(T'(1, 0)\)
