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) ....

what level of math? also i don't need to be paid if i can you.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
