On a coordinate plane, point A is at (3, 3) and point B is at (negative 3, 3). Point B is the image of point A when A is rotated

Vladimir [108]

Answer:

Point B must be at the same distance from the the origin as point A.

Step-by-step explanation:

Coordinates of point A = (3, 3)

When point A is rotated 90° counterclockwise around the origin, coordinates of the new point B will be (-3, 3)

Distance from origin to point A = $\sqrt{(3)^{2}+(3)^2}=3\sqrt{2}$

Similarly, distance of point B from the origin = $\sqrt{(3)^{2}+(3)^2}=3\sqrt{2}$

Therefore, distances of both the points from the origin are same.

Point B must be at the same distance from the the origin as point A.
