To find the coordinates of vertices P and R in rectangle PQRS, we can use the information given about vertices Q and S, and the properties of rectangles.

  1. Understanding the positions of Q and S:

    • The coordinates of Q are \( Q(4, -2) \).
    • The coordinates of S are \( S(-1, 3) \).
    • Since the rectangle is labeled counterclockwise, \( Q \) and \( S \) are adjacent vertices.
  2. Finding the coordinates of vertices P and R:

    • The vertices of a rectangle are defined such that opposite sides are parallel and equal in length.
    • The coordinates for R will correspond to Q along the same line (horizontal or vertical) as S, and coordinates for P will correspond to S along the same line as Q.
  3. Finding P:

    • Since Q and S share a vertical line, we can maintain the x-coordinate of S with the y-coordinate of Q to find P.
    • Therefore, the coordinates of P are: \[ P = (x_q, y_s) = (4, 3) \]
  4. Finding R:

    • Similarly, since Q and S share a horizontal line, we can maintain the y-coordinate of S with the x-coordinate of Q to find R.
    • Therefore, the coordinates of R are: \[ R = (x_s, y_q) = (-1, -2) \]
  5. Final Coordinates:

    • The coordinates of vertices P and R are:
      • \( P(4, 3) \)
      • \( R(-1, -2) \)

To summarize, the positions are:

  • \( P(4, 3) \)
  • \( R(-1, -2) \)
