Answer 1

To determine the new coordinates of point A (2, 4) when the triangle is rotated 90 degrees clockwise, we can use the rule for rotation of coordinates:

When a point (x, y) is rotated 90 degrees clockwise, the new coordinates become (y, -x).

Applying this to point A (2, 4):
- x = 2
- y = 4

After rotation:
- New x-coordinate = y = 4
- New y-coordinate = -x = -2

Thus, the new coordinates after a 90-degree clockwise rotation are (4, -2).

So, the correct response is:

**(4, −2)**
