It's a right angle!!!!!!!!!

Reflection Activity

I reflected the triangle over the line which starts in the bottom left of the image. The reflection overlaps the original image, but is pointing the opposite way. All the points are on opposite points on the same Y coordinate. The shift is a 180 degree flip. 

A: (6,0) B: (-2,3) C: (-1,-3)

A': (-6,0) B': (2,3) C: (1,-3)

X=0

I reflected this shape over the center line. The shapes overlap to except for at the ends. They both have the same Y coordinates. The shift is a 180 degree flip.
A,B,C,D
A'B'C'D'
X=0

I reflected the rectangle over the top line. This reflection barely overlaps and is congruent with the other shape. The shift is an upward turn forming an acute angle between the two shapes.

A,B,C,D

A'B'C'D

Y=4

Chain of Reasoning

If chocolate is good, then people fight over it.
If people fight over chocolate, someone will get hurt.
If someone gets hurt, they will have to wear a bandage.
If someone wears a bandage, they will get sympathy.
If someone gets sympathy for wearing a bandage, they will fake an injury.
If you fake an injury, then someone will find out.
If someone finds out, then they will be mad.
If someone is mad at you, you will be sad.

Therefore: If chocolate is good, then you will be sad.
