Graph the image of the given triangle after a rotation of 180° about the origin. Select the Polygon tool. Click the points of the triangle vertices to create the triangle by connecting the sides.

(Pictorial representation is provided in the attached image.)

The given triangle's coordinates are (-1, 1) (-2, 6) (-5, 4)

When we rotate any polygon by 180° in a Cartesian plane, we simply change the positive coordinates to negative and vice versa.

Thus, the coordinates of the now rotated triangle are,

(1, -1) (2, -6) (5, -4)

Hope this helps :)
