Given point A(2, 4) on the triangle in quadrant 1 where is the new point if the triangle is rotated 90 degrees counterclockwise
To rotate a point 90 degrees counterclockwise, we can switch the coordinates of the point and then negate the new x-coordinate.
Given point A(2, 4), to find the new point after rotating it 90 degrees counterclockwise:
- Switch the x and y coordinates: A(4, 2)
- Negate the new x-coordinate: A'(-4, 2)
Therefore, the new point after rotating A(2, 4) 90 degrees counterclockwise is A'(-4, 2).
