Answer:
It is a reflection of triangle 1 in the y-axis.
Step-by-step explanation:
The y coordinates are unchanged but the x coordinates have change sign.
Triangle 2 is the reflection of triangle 1 in the y-axis.
When a shape is reflected, it must be reflected across a line.
Triangle 2 is a reflection of triangle 1, across the y-axis
The vertices of triangle 1 are:
[tex]\mathbf{Triangle\ 1 =(A,B),(C,D), (E,F)}[/tex]
The vertices of triangle 2 are:
[tex]\mathbf{Triangle\ 2 =(-A,B),(-C,D), (-E,F)}[/tex]
When a point is reflected across the y-axis, the transformation rule is:
[tex]\mathbf{(x,y) \to (-x,y)}[/tex]
This means that:
Triangle 2 is a reflection of triangle 1, across the y-axis
