The coordinates of vertex c after a reflection across the x-axis are (8, -1)
How to determine the coordinates of vertex c
From the question, we have the following parameters that can be used in our computation:
Quadrilateral ABCD
Also, we have
a (-4-3), B (3,-4), c(8,1) and d (1,2)
The transformation rule is given as
reflection across the x-axis
Mathematically, this is represented as
(x, y) = (x, -y)
Using the above as a guide, we have the following:
C' = (8, -1)
Hence, the coordinates of vertex c after a reflection across the x-axis are (8, -1)
Question
an enclosure shaped like a quadrilateral ABCD is erected in a park assuming that a park is a coordinate plane, the post of the enclosure can be represented by vertices a (-4-3), B (3,-4), c(8,1) and d (1,2)
