Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.

A) Reflection

B) (-2,-6)

Step-by-step explanation:

Have a look at the attached picture:

The type of transformation that maps ∆ABC onto ∆A′B′C′ is a reflection across the x-axis. A reflection is an isometry, which means the original(pre-image) and image are congruent, that can be described as a "flip".

When ΔA'B'C' is reflected across the line x = -2  to form ΔA"B"C", the vertex of ΔA"B"C" will have the same coordinates as B' which is (-2,-6) ....

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
