Which quadrilaterals have a diagonal that is also a line of symmetry?
A square
What does one line of symmetry means?
If you had a circle and you halved it, exactly in the middle, then that line would be a line of symmetry! And it is the same with a square. If you halve it exactly in the middle then that would be called a line of symmetry! And then all the lines of symmetry in a square are down, across, diagonal from the left and then diagonal from the right! But in a circle there are LOTS of lines of symmetry!
Does z have a line of symmetry?
It has a line of rotational symmetry - along the diagonal.
What is the line that divides a square in two called?
Oh, dude, it's called a diagonal. Yeah, like when you draw a line from one corner to the opposite corner of a square, that's the fancy term for it. It's like the square's way of saying, "I'm not just a boring ol' four-sided shape, I've got some flair with my diagonals."
Why parallelogram has no lines of symmetry?
If you draw a diagonal line from corner to corner of a parallelogram, that is a line of symmetry.
