Answer the questions by drawing on the coordinate plane below.
draw the image of ∆pqr after a counterclockwise rotation of 90° about the origin.
label the image ∆p'q'r'.

The image ∆P'Q'R' on the coordinate plane is attached.

Step-by-step explanation:

A rotation is defined as a transformation in which a figure is rotated about   a point called "The center of rotation"

The Rule for 90° counterclockwise rotation about the origin is:

→

 Observe in the picture that the coordinates of the vertices of the triangle PQR are :

Therefore, applying the Rulefor 90° counterclockwise rotation about the origin we get that the coordinates P'Q'R' are:

Knowing these coordinates, you can draw it on the coordinate plane (Observe the picture attached)
