The new coordinates of the triangle after reflection from x-axis would be A(-2, -3) , B(0, -3) and C( -1, 1 )
Explanation:
The vertices of the triangle are A(-2 3), B(0,3), C(-1,-1)
The reflection is over the x-axis.
When the reflection is along the x-axis, the coordinates of x does not change. However, the coordinates of y does change.
The negative value of y becomes positive and the positive value of y becomes negative.
Similarly,
A(-2, 3) would become A(-2, -3)
B(0, 3) would become B(0, -3)
C(-1, -1) would become C( -1, 1 )
Therefore, the new coordinates of the triangle after reflection from x-axis would be A(-2, -3) , B(0, -3) and C( -1, 1 )
