Intro

Ex. 1:

<p>- Hi, welcome to this question right here. So, this question here's trying to find and draw all the lines of symmetry on the figure. Remember you had a vertical line, horizontal line and something that's called oblique lines, right? So you if you look at this figure right here if you're trying to draw the lines symmetry you just have to think, this line kind of represents the mere. So if you cut it down, it's going to form something that's called the symmetrical images. So, I guess you probably have two for this one, check it out. So if you join a line down this way right here, a vertical line down this way, you will see that these two sides are now symmetrical. This is called the vertical line of symmetry. Now, there is another one. The other one right here will be if you just cut it across like right in the middle right here, the top and the bottom will also form the symmetrical images and this line right here is called a horizontal line, horizontal line of symmetry, okay? So, I think there's only two right here. I bet I guess you can't really cut into half the other way around. So there's only two. Thanks for watching.</p>

Objects which have line symmetry or reflection symmetry can form symmetrical images where they are cut by an imaginary line that is called line of symmetry. An object can have more than one lines of symmetry.
