In this question, we are told to do a 90 degree rotation.
00:06
And what you'll see is that i put counterclockwise.
00:09
So because it is a positive 90 degrees, we always know that we're going counterclockwise because that is positive.
00:16
So we're going to go a whole 90 degrees.
00:19
And i also put down our kind of formula that it normally follows.
00:24
So my x value goes to my y value and then my y value goes to my x value.
00:29
Kind of flips over.
00:31
Okay, so let's talk about this for a moment.
00:34
It doesn't necessarily give us an x and y coordinate.
00:37
However, what we can do is we can kind of make our own using the point a that they give us as our origin of zero zero.
00:45
So if i do that, i can label each of these sides as a point.
00:50
So i've got two, two, i've got four two, i've got two, four, and then i have four, so.
01:02
I have four, so.
01:02
So i've got two, okay.
01:05
So if we follow our format of what happens, so 2 -2 is going to go to negative 2, 2...
