Question

Which statement accurately describes how to perform a 180° rotation of point A (−2, 3) around the origin? A) Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 180° from point A. B) Create a circle with point A as its center and a radius of the origin and point A, then locate a point on the circle that is 180° from point A. C) Create a line parallel to the x‒axis from point A, and locate a point on the perpendicular line that is equidistant to the distance between the y-axis and A. D) Create a line perpendicular to the y-axis from point A, and locate a point on the perpendicular line that is equidistant to the distance between the y-axis and A.

Answer 1

A) Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 180° from point A.

Explanation:

• The first step is to place your compass at the origin (0,0)

• Adjust the compass to a radius which equals the length of A from the origin

• Draw the circle to locate the rotated point A' on the circle which is 180° from point A
