Question

The vértices of polygon ABCD at A(1,1), B(2,3), C(3,2), and D(2,1). ABCD is reflected across the x-axis translated 2 units up to form polygon A’B’C’D’ to its coordinates.

Answer 1

Answer:

A' - 1,1

B' - 2,-1

C' - 3,0

D' - 2,1

Step-by-step explanation:

in order to do this problem, you would first reflect every point over the X axis. this then makes it a polygon in quadrant 4. from there, you would move each point up 2 points. this would mean that every X value stays the same. the only value that changes in this scenario is the Y value. This is not always true so do not use this rule unless you know for sure. Hope this helps!!
