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′.

Reflection

Step-by-step explanation:

When we reflect a point on the x axis, the y coordinate changes its sign.

For example if a Point P has coordinates (x,y), it will be (x, -y) after reflection on the x axis.

A (-6,2) reflected on the x axis becomes A' (-6, -2)

B (-2,6) reflected on the x axis becomes B' (-2, -6)

C (-4,2) reflected on the x axis becomes C' (-4, -2)

So, the type of transformation that maps ∆ABC onto ∆A′B′C′ is a reflection on the x axis.

answer: the common difference is -0.10
