Rotation can go two ways. It can got clockwise which is rotating right. Also it can go counterclockwise which is rotating left. The formulas for clockwise are 90 degrees (x,y)=(y,-x) 180 degrees (x,y)=(-x,-y) 270 (x,y)=(-y,x). And the formulas for counterclockwise are 90 degrees (x,y)=(-y,x) 180 degrees (x,y)=(-x,-y) 270 (-y,x).

The problem is #3
Reflection over the line y=x
Formula:(x,y)=(y,x) Flip the x and y pair.
A(3,-4)=(-4,3)
B(1,-6)=(-6,1)
C(-2,-3)=(-3,-2)
D(3,1)=(1,3)
Then plot it on the graph.
My name is Jaelon Brown. I was born in Montgomery but I’m from Wetumpka. For fun I like to play or watch sports. I play football. My hobby is traveling. I have 1 brother 1 sister. I have 1 dog.
My goal in your class is pass with a high B or A. My goals the year are to a honor royal student. My goal for high school is to graduate and hopefully get 3 state championships. My goals after high school are to go to college and graduate with a 4 year degree.
11.AC
First you find AB and BC.
AB=4.9 BC=5.2
4.9+5.2=10.1
So AC=10.1
35. J(-4,2) F(5,-2)
Formula: (x1+x2/2,y1+y2/2)
(-4+-2/2 ,2+5/2)
-4+2/2=-3
2+5/2=4.5
So the midpoint is (-3,4.5)
Vertical angles have two angles across from each other on inserting lines. They are also congruent. Adjacent angles have two angles that are next to each other and share a common side. Linear pairs have two angles that are adjacent and supplementary. Complementary angles are any two angles whose sum of 90°. Supplementary angles are any two angles whose sum is 180°
