Each triangle in the diagram is a reflection of another triangle across one of the given lines. how can you describe triangle 3 by using a reflection rule?

a. rm
(triangle 2)

b. rm
(triangle 1)

c. rl
(triangle 1)

d. rl
(triangle 2)

Looking at the given figure above, the correct answer would be option D. Rl triangle 2. To describe triangle 3 using the reflection rule, we can say that Triangle 3 is a mirror reflection of Triangle 2 with respect to line l. The reflection rule is is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a set of fixed points. In other words, it is a flip.

Rearrange the equation so that 

g= 2/5 divide 3/5

g= 2/5 X 5/3

g= 10/15

g= 2/3
