Question

Confused...

Answer 1

@jim_thompson5910 I'm so confused with quadrants and rotations...

Answer 2

To rotate any point (x,y) 90 degrees clockwise about the origin, you simply flip the coordinates to get (y,x) and then you change the sign of the second coordinate to get (y,-x)


So for example, rotating the point (-2,5) 90 degrees clockwise about the origin gives you (5, 2)

Answer 3

@jim_thompson5910 Someone told me it was -5, 2? so that's not right?
