The two lines of reflection are and
Step-by-step explanation:
I will attach a file with the graph of the rectangle and the lines of reflection.
We know that RSTU is a rectangle with vertices at ,
,
and
The first step is to draw the vertices on the plane and them the rectangle.
The rectangle is a symmetrical figure. Therefore if we want to carry the rectangle onto itself using a line of reflection this line must goes through the centroid of the rectangle.
Given that we have a rectangle whose width is and its length is
its centroid will be place at
.
Looking at the graph and using this information we find that the two lines of reflection are and
.
Answer:
PA = 8
Step-by-step explanation:
formula is C^2 = E * (A + E)
C^2 = 4 * (12 + 4)
C^2 = 64
c = 8
C = PA = 8
