Question

Give point A (2, 6) on the triangle, what are the new coordinates of the point after the triangle is rotated 90 degrees counterclockwise?

Answer 1

To rotate a point 90 degrees counterclockwise, the x-coordinate becomes the negative value of the original y-coordinate, and the y-coordinate becomes the original x-coordinate.

Given point A (2, 6), the new coordinates after rotating 90 degrees counterclockwise can be found as:

- The new x-coordinate = -6
- The new y-coordinate = 2

Therefore, the new coordinates of point A after the triangle is rotated 90 degrees counterclockwise are (-6, 2).
