Question

Quadrilateral \[tram\] is rotated \[-90^\circ\] about the origin.

A) 90-degree counterclockwise rotation
B) 180-degree rotation
C) 270-degree clockwise rotation
D) No change in orientation

Answer 1

The correct answer is (A) 90-degree counterclockwise rotation.

Step-by-step explanation:

The correct answer is (A) 90-degree counterclockwise rotation.

In a 90-degree counterclockwise rotation, the vertices of the quadrilateral are rotated 90 degrees in the counterclockwise direction around the origin.

For example, if the point (x, y) represents a vertex of the quadrilateral, after the rotation, the new coordinates of the vertex will be (-y, x).
