Question

Now check your predictions. In GeoGebra, rotate quadrilateral ABCD about the origin through angles of 90°, 180°, 270°, and 360°. Enter the coordinates of the vertices of quadrilateral A′B′C′D′ in the table. Paste a screen capture of the images you created below the table.

Answer 1

(−3, −2) (−2, −1) (−1, −2) (−1, −4)

Angle of Rotation (CCW)

90° (2, −3) (1, −2) (2, −1) (4, −1)

180° (3, 2) (2, 1) (1, 2) (1, 4)

270° (−2, 3) (−1, 2) (−2, 1) (−4, 1)

360° (−3, −2) (−2, −1) (−1, −2) (−1, −4)
