#

So I’m kinda confused

#

#

I know the rule for rotations with 90 degrees is flip x and y and negate the new x

#

But these points are wrong right?

Your overcomplicating it

#

U dont need negative x and y and allat

#

How do I make it easier?

#

Draw a right angle between the origin and each of the points

#

And rotate 90 anticlockwise

#

@woeful acorn whe u at vro

#

Yo

#

can you give an example

#

i’m kinda confused

#

ok

#

@woeful acorn

#

Drawn a right angle from origin to R

#

Then rotated that 90 anticlockwise

woeful acorn Dec 3, 2025, 1:42 AM

#

I think I understand

stable cradle Dec 3, 2025, 1:43 AM

#

So do that for all points

#

And join em up
