This week in geometry, I learned about symmetry. A line of symmetry is a line that goes through a shape that forms a reflection of both Screen Shot 2016-05-18 at 9.35.31 PMsides. An example would be in the image on the right. That line makes both sides of the shape reflections of each other. This shape only has one line of symmetry. Other shapes could have two or more lines of symmetry, or just no lines of symmetry. You have to be watchful. I hope you learned something.
