Asequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is
when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex (note: enter your response using apostrophes instead of
of ∆a″b″c″ will have the same coordinates as b′.

Reflection

(I don't know the second blank, sorry!)

Step-by-step explanation:

The triangle is being reflected over the x-axis.
