Answer:
Reflection line is x axis .
Explanation:
Given : Pentagon PQRST and its reflection, pentagon P'Q'R'S'T', are shown in the coordinate plane below.
To find : What is the line of reflection between pentagons PQRST and P'Q'R'S'T'?.
Solution : We have given
Parent pentagon = PQRST.
Reflected pentagon = P'Q'R'S'T'.
Coordinate of pentagon P ( -4 ,6 ) ; Q (-7 ,4) ; R (-6 ,1) ; S (-2 ,1); T(-1 ,4).
Coordinate of pentagon P' ( -4 , -6 ) ; Q (-7 , -4) ; R (-6 ,-1) ; S (-2 ,-1); T(-1 ,-4).
By the reflection rule across x axis : (x ,y) →→ ( x , -y).
Then it is reflection line is x axis .
Therefore, reflection line is x axis .
