Question

Which figure shows a reflection of pre-image QRS over the line t?

Answer 1

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)
