Asked by Deborah

Triangle ABC has coordinates A(1, 4); B(3, –2); and C(4, 2). Find the coordinates of the image A'B'C' after a reflection over the x-axis?
I have never done one where the triangle is already over the x-axis...do we flip it up or down...
Please help me figure this out...

A(1,4) ---> A'(1,-4)
B(3,-2) --->B'(3,2)
C(4,2) ---> C'(4,-2)

Can you see what happened?
Plot he original and then the new one, use different colours to draw the lines of each triangle and notice the result.
