Don't forget class, our test on reflections is 2 days away.
Sure, let's meet at your house at 5.
OMG HE IS TALKING TO ME!!!!
Do you think you could help me prepare for the test?
Let's look at a square first.
OK! Let's get started! Where do we start?
And... how did you know where I lived?
I guess that makes sense, this is tiring though. My brain might melt...
No silly. You don't actually fold stuff in half, it just perfectly reflects the other side of the shape if the shape has symmetry.
Wait, so like, I could fold my water bottle in half if I used the line of reflection? COOL!
If you take a square and fold it in half, you get a rectangle right? Well, a reflection is essentially a line folding th square in half. As you can see by the dotted line, if you folded the square across it, you would perfectly match it. That line is called the line of reflection.
The same thing happens if you take a triangle and put the line of reflection straight in the middle. It also works on a trapezoid.
No! First, it wasn't a movie - it was an educational video-, and second, there is NO such thing as a magic pencil.
This is so weird. It works on all shapes... Kinda like a magic pencil? Like the one in the movie that Mr. Connelly showed us?
There are certain types of shapes that do not have reflectional symmetry. Sometimes, like in this triangle, the line of reflectional symmetry is not vertical but it can also be angled. A bunch of objects in life can be reflected and it is a very important skill to understand.
