Graph a triangle (LMN) and rotate it 180° around the origin to create triangle L′M′N′.

1.Describe the transformation using words. Make sure you refer to the characteristics and the coordinates.
2.Draw a line through points L and L′ and through M and M′. What do you notice about the lines you drew? Do you think you would notice the same characteristics if you drew another line through points N and N′? How do you know?

Well first create a triangle, create any 3 points that connect and make a triangle [I suggest: (5,5), (3,3), (7,3) ] The rotation rule is (x,y)-> (-x,-y) [Basically negate the sign of the x and y values] You should get something like this https://www.desmos.com/calculator/jx3mcpuc08
