Problema Solution
The vertices of parallelogram ABCD are A(2 , 1), B(3 , 4), C(5 , 3), and D(4 , 0). ABCD is reflected over the x–axis to create parallelogram QRST. What are the coordinates of QRST?
Answer provided by our tutors
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite:
A(2 , 1) -> Q(2 , -1)
B(3 , 4) -> R(3 , -4)
C(5 , 3) -> S(5 , -3)
D(4 , 0) -> T(4 , 0)
