Question

The coordinate of point A on the circle in the following graph, after being rotated 270° in the clockwise direction around the origin will be .

• A. (0,0)
• B. (4,0)
• C. (0,-4)
• D. (0,4)

Answer 1

The correct option is C (0,-4)


The rotation transformation turns the figure around a point. In this case, the reference point is the origin, i.e., (0, 0).

Rule for clockwise rotation of 270°:
(x, y) → (y,x)

So, the coordinates of point A(-4,0) after rotating 270° clock wise will be (0,-4).
