Does the following figure have a line of symmetry?

We’re shown a shape. We have to work out if it has a line of symmetry. If you were to fold the shape in half to make each side equal, where would you fold it? Could this be the line of symmetry? If you were to place a mirror along this line of symmetry, this is what you’d see. This means that the shape is symmetrical. The answer to the question is yes, this figure does have a line of symmetry.
