Answer:
Figure 1 (Reflection about line t)
Step-by-step explanation:
We are given three image of reflection across line t
Reflection: Distance of coordinate from line is equal and exactly same direction. (Line joining the point Q and Q' must be perpendicular to line t)
Distance of S and S' from line t must be equal.
Distance of Q and Q' from line t must be equal.
Distance of R and R' from line t must be equal.
In Figure 1:
Q is 5 unit from line t and Q' is 5 unit from line t (TRUE)
R is 7 unit from line t and R' is 7 unit from line t (TRUE)
S is 2 unit from line t and S' is 5 unit from line t (TRUE)
In figure 2:
Q is 5 unit from line t and Q' is 5 unit from line t but QQ' not perpendicular to line t. (FALSE)
In figure 3:
R is 7 unit from line t and R' is 2 unit from line t (FALSE)
Hence, Figure 1 is reflection about line t (Please find attached file for figure name)
