Question

1. what happens to a point when it is rotated 180 degrees around the origin?

a. both coordinates are negated
b. both coordinates remain unchanged
c. the coordinates are swapped and the new y - coordinate is negated
d. the coordinates are swapped and the new x - coordinate is negated

Explanation:

When a point (x, y) is rotated 180 - degrees around the origin, the new coordinates become (-x, -y). This is because a 180 - degree rotation is equivalent to a reflection through the origin.

Answer:

A. Both coordinates are negated
