Q:

A sequence of transformations maps ∆ABC onto ∆A″B″C″. The type of transformation that maps ∆ABC onto ∆A′B′C′ is a reflection.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′.

Accepted Solution

A:
The transformation that maps ΔABC onto ΔA'B'C' is a reflection across the x-axis (or across the line y = 0).When ΔA'B'C' is reflected across the line x = -2 (shown in the figure) to form ΔA"B"C", the vertex of ΔA"B"C" will have the same coordinates as B', which is (-2,-6)
