Question

Draw a real-life object that has only a horizontal line of symmetry.

Answer 1

Hint: We solve this question by using the concept of symmetry. We need to know the meaning of a horizontal line of symmetry first. After explaining this, we should give a real-life example of an object that has a horizontal line of symmetry.

Complete step-by-step solution:
In order to solve this question, let us first explain what a horizontal line of symmetry is. It is a horizontal line passing through as an object such that it divides the object into two symmetrical halves. A symmetry means that the two images or two halves of an image are coinciding when we overlap them.
In the case of a horizontal symmetry, we have a horizontal line passing through the middle of the image and when the image is folded along this line, we get the two halves overlapping and coinciding perfectly. An example for this could be a square or a rectangle or any other object that is symmetric horizontally.
A real-life example for the same could be the road sign of an arrow indicating the direction to move in. This is given in the figure below.

Now, we can say this figure is horizontally symmetric. This can be shown by drawing a horizontal line through the mid-point of this figure as shown below.

Now, we shall fold this along the horizontal symmetry line upwards to see if the image is completely overlapping and coinciding. Doing this, we obtain

Since the two halves of the images are exactly overlapping and coinciding, we can say that the image has a horizontal line of symmetry.

Note: We need to know the concept of symmetry in order to solve this sum. We can also solve this question by folding the same image downwards such that the upper half is overlapping with the lower half. This also provides the same results that the two images overlap and coincide. Hence, the object has a horizontal line of symmetry.
