Question

Match the following items. In the figure below, several reflections are illustrated. Note one line of symmetry is m and one is l. Pay close attention to the line of reflection being indicated by R l and R m.

Answer 1

$R_I$
This means that the line of symmetry is line I.

$R_m$
This means that the line of symmetry is line m.

1. $R_I:T$
This matches with Q.
In this number, the line of symmetry is I. If you reflect T across line I, you will get point Q. This is because they are right across from each other with line I between them, and they are both the same distance from line I.

2. $R_I:S$
This matches with S.
Point S lies on the line of symmetry; thus, S reflects itself.

3. $R_I:Z$
This is similar to number 1. If you reflect Z across line I, you will get point X because they are directly across each other with line I between them and they have the same distance from the line of symmetry.

4. $R_m:S$
This time, S isn't on the line of symmetry. The line of symmetry is the vertical line m. Point Y matches with point S because they are directly across each other with line m between them. They are also the same distance apart from line m.

5. $R_I:B$
This is very similar to number 1. This matches with F. The point directly across the line of symmetry is F.

6. $R_I:F$
This is the exact same as number 5! With the same line of symmetry, B matched with F. Thus, F must match with B!

Here are the matches:
3-X
5-F
6-B
4-Y
1-Q
2-S
