Answer 1

To find the coordinates of the vertices of triangle \( \Delta PQR \) after rotating it 90 degrees counterclockwise about the origin, we can use the following transformation rule:

If a point has coordinates \( (x, y) \), then after a 90-degree counterclockwise rotation about the origin, the new coordinates \( (x', y') \) will be given by: \[ (x', y') = (-y, x) \]

Please provide the original coordinates of points \( P \), \( Q \), and \( R \) so that we can perform the rotation and find \( P' \), \( Q' \), and \( R' \). Feel free to share a list of these coordinates.
