Question

Janie uses a reflecting tool to reflect Point B onto Point A. Which of the following statements are true about the line of reflection?
1. Reflection line is perpendicular to AB
2. Reflection line does not bisect AB.
3. Reflection line passes through the midpoint of BA.
4. Reflection line forms two equal angles with segment AB.

Answer 1

1. perpendicular would mean the line of reflection would look like this:

Answer 2

if you took a piece of paper, drew a line on it, and folded it so that one end of the line went over the other end of a line, the crease on the paper where you folded it in half would be the bisection of the line a-b. so 2 does not seem correct.

Answer 3

Oh, I get it now! Thank you. :)

Answer 4

if the reflection line formed two equal angles with B and A, how would you draw that? could it look something like this? That doesn't seem to be a way to make A and B cover each other. So it does not seem as if the final answer could be correct.

Answer 5

(i always make origami with my reflections in my head. For a really fun easy way to remember this: search on youtube for "gagnam style math" and practice trying to dance really really hard. You will NEVER forget it!
