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.

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!!

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
