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?

The triangles are similar. what is the value of x? show your work.

Which statement accurately explains whether a reflection over the y-axis and a 270° counterclockwise rotation would map figure acb onto itself? a coordinate plane with figure acb with point a at 1, 1, c at 3, 4 and b at 5, 1 yes, a″c″b″ is located at a″(1, 1), c″(4, 3), and b″(1, 5) yes, a″c″b′ is located at a″(1, 1), c″(3, 4), and b″(5, 1) no, a″c″b″ is located at a″(1, 1), c″(4, 3), and b″(1, 5) no, a″c″b″ is located at a″(1, 1), c″(3, 4), and b″(5, 1)

Are the corresponding angles congruent? explain why or why not.
