Because they are perfectly symmetrical. go ahead and draw a square then look at it in the mirror :)

What happens to the light rays as they hit the mirror at an angle?
they are reflected at an equal opposing angle on a first-surface mirror. on a second surface (bathroom mirror) they are also reflected, but some are absorbed/disbursed by impurities and inconsistencies in the glass.
Why some letters don't have line of symmetry?
Some of the letters don't have a line of symmety because some are not equally the same size.
What is a line of symmetry in letters?
It is the same as in shapes, the ability to be divided into two equal halves either vertically or horizontally. Not all letters have a line of symmetry, and some have two (H, X, O).
What are some shapes that look exactly the same when seen as a reflection in a mirror?
Everything that is seen as a plane mirror reflection is left/right reversed. This reversal might not be as apparent, with some shapes. A sphere for example, might require very close scrutiny to see that its reflection is left/right reversed, but it is always so. The same reasoning may be applied to any object with left/right symmetry.
The color you see when you look in a mirror is the color of whatever is reflected in the mirror but does a mirror have its own color?
Of course. Mirrors do not reflect every color the same. Usually you would not notice this, because mirrors are desireable because of the lack of color in the reflection. Mirrors can be made of many things, copper (used for lasers), aluminum (used for telescopes), rhodium (used for some optical devices). They each have characteristic reflectivity at various wavelengths. Spacecraft often have mylar coated with gold reflective insulation because it has great reflectivity in the infrared to reflect the heat from the Sun. Of course it looks golden-yellow-green to us. To directly view the colors of various mirrors, simply observe various metal samples. For example, compare the color of a silver spoon with a stainless steel spoon, and hold both near a flat piece of aluminum foil. Mirrors made from the same metals will show these same colors.
What are the conditions for seeing the image of an object in a plane mirror?
-- Light has to shine on the object, and some of it has to reflect off of the object. -- Some of the reflected light has to make it to the mirror. There can't be any physical obstruction in the path. -- The mirror has to be clean enough so that some of the light hitting the mirror is reflected away from it. -- Your eye has to be on the path taken by the light after it reflects from the mirror.

Why does sunlight reflected off a mirror onto an already sunlit surface appear to be much brighter?
When sunlight hits the wall it is reflected back in all directions. Some of it hits your eye and some of it hits the mirror. The light that hits the mirror re-reflected back to its source and strikes the wall again. That light is then re-re-reflected of the surface and some of it reaches your eye. Basically, the light that would have normally gone elsewhere is given a second chance to reach your eye.
Which letters of the alphabet that are reflected over a vertical line look the same?
Some letters are: T, A, l, I, O, o, i, Y, W, w, H, X, x, V, v As you can see, there are a lot of letters. Depending on how you write some letters, there could be more or less.
How is a reflection of light off a white wall similar to the reflection of light off a mirror?
when light hits an object some light is absorbed and some is reflected. when it hits a mirror, almost all of that light is reflected. when it hits a white wall a lot of the light is reflected but not enough to form an image our i can detect. a wall is also not smooth so the light is reflected at billions of different angles
What happens when light falls on mirror?
It is reflected. Depending on the shape of the mirror, this can be at a variety of angles. Assuming the question refers to a flat mirror that is hung on a wall; a plane (flat) mirror has an imaginary straight line at a right-angle to it, called the normal. A ray of light hits the mirror at an angle to the normal, but is reflected at the same angle that it hits the mirror in the opposite direction. So if a ray hits the mirror at 45 degrees from the normal, it will be reflected at 45 degrees from the normal in the opposite direction.
What happens when light hits a reflective surface?
It reflects with the angle of incidence (angle between the original ray of light and the normal (90 degrees to the mirror surface)) being the same as the angle of reflection (angle between the reflected ray of light and the normal). Some of the light energy is transferred into heat energy by the mirror, so the reflected beam is less bright than the original beam, but the difference is barely noticeable on a clean mirror.
What is the cause of lateral inversion?
It is caused by front to back inversion. Right and left have meaning only when front is specified. When we look into the mirror, suppose we have left sleeve as green and right sleeve as red. They are indeed on the same side in the image. Is it not so? But the image is facing opposite to us. So for the mirror person green becomes right and red becomes left. Write some letters on a translucent paper. See this paper in the mirror. Some of the letters are laterally inverted (depending on their symmetry). Now see the same paper from the back side. Does it not look like the image of the front side in the mirror? The cause is, of course, that the light ray starting from the object is reflected back and hence whatever looked towards the mirror now looks out of the mirror. That is why I call it "front-back" inversion. COMMENT, to clarify things a little: I agree it is "front-back" inversion in terms of the physics. The object and image are reversed in the direction perpendicular to a (flat) mirror's surface. However, depending on the object, the image often SEEMS to be left-right reversed. That's why it's called "lateral" (sideways) inversion.
If a glass is transparent why do you see mirror images of ourselves when you look out the window of a lighted room?
Because glass is not perfectly transparent, some of the light is reflected
How does a concave mirror affect light?
A concave mirror will tend to "focus" light to some degree, depending on the curvature of the mirror. A parabolic mirror will bring reflected light to a sharp focus, and telescopes use this type of curve for the shape of their reflective surface. And for exactly the reasons you think they do.

If you shine a flashlight at a mirror what does it prove?
When you shine a flashlight at a mirror it proves that you are able to turn the flashlight on. The reflection of that light can be used to demonstrate some basic principles of optics, such as that the angle of incidence equals the angle of reflection. It proves that the flashlight is in working order, that you are able to direct the light toward the mirror, that the light is reflected by the material at the back of the mirror, that the mirror itself is opaque, and that you have access to a mirror and a flashlight.
What letters are in the Malay alphabet?
They are exactly the same as the letters of the English alphabet, but some letters have different sounds.
