The capital letters H, I ,O and X all have both horizontal and vertical line symmetry.Īll the rest of the letters (F, G, J, K, L, N, P, Q, R, S and Z) have no line symmetry. It would be easy to draw a capital B that did have horizontal line symmetry-this one almost does. I can't tell that without actually flipping it upside down or measuring, though, so I left it in my list. Actually, even though I included B (and maybe you did too), B isn't perfectly symmetric in the Arial font because the top loop of the B is just a tiny bit smaller than the bottom loop. I see horizontal line symmetry in the captial letters B, C, D, E, H, I, O and X. Alphabets having both horizontal and vertical mirrors are H, I, O, X. I see vertical line symmetry in the capital letters A, H, I, M, O, T, U, V, W, X and Y (some of these have other kinds of symmetry too!) Alphabets having a reflection symmetry about a horizontal mirror are B, C, D, E, H, I, O, X. Even among san serif fonts, symmetry can be slightly different, so my answers may be different from yours if I write my letters differently. Arial is a san serif font-all of those extra bits are missing in an Arial font-that makes the letters have more symmetry. They are useful to have somewhere in the classroom so that when symmetry is discussed there are some examples that can easily be used. I'm using the Arial font, which is a san-serif font. Serifs are the little fancy bits on the ends of letters: Times is a serif font-f's have little lines at the bottom, and S's have little lines at the top and bottom, and A is thinner on the left side than the right side. These colourful and printable letters of the alphabet show the degrees of rotation and the reflective symmetry. It all depends on just how you draw your letters. This can be observed clearly from the figure given below. What letters of the English alphabet have reflectional symmetry i.e., symmetry related to mirror reflection about. In other words, it is defined as the sliding of an object about an axis. If the object is translated or moved from one position to another, the same orientation in the forward and backward motion is called translational symmetry. we get an equivalent equation.Introduction to Symmetry Line symmetry in capital letters syn- together + metron measure Reflection Symmetry The simplest symmetry is Reflection Symmetry (sometimes called Line Symmetry or Mirror Symmetry ). Reflection Symmetry Glide Symmetry Translation Symmetry. A circle with center at the origin and radius r >0 has equation x 2+ y 2= r 2. Show algebraically that a circle with center at the origin is symmetric with respect to the origin. If you end up with the exact opposite of what you started with (that is, if f (–x) = –f (x), so all of the signs are switched), then the function is odd.Īre circles symmetric with respect to the origin? To do this, you take the function and plug –x in for x, and then simplify. You may be asked to “determine algebraically” whether a function is even or odd.

In fact, all the letters of the English alphabet except G, Q, and V have reflection symmetry. symmetry Reflection symmetry in two directions This ray is not bent. ![]() It also makes components, such as gears, wheels, and axles, easy to make out of solid cubes or other polyhedra. If the resulting equation is equivalent to the original equation then the graph is symmetrical about the origin. This reflection symmetry is very important for creating looking artificial objects out of cubes or other polyhedra. Test for symmetry about the origin: Replace y with (-y) AND x with (-x). It is a standing line that divides the pattern into their replicating halves. If the line passes through the pattern from top to bottom, hence dividing the pattern into identical halves, then such line is the vertical line of symmetry. If you make the top smaller than the bottom, it has only one vertical line of symmetry. Some letters look the same when facing a mirror.Ĩ has two lines of symmetry and 180 degree rotational symmetry if you draw the top and bottom the same size. “H” and “I” have both vertical AND horizontal symmetry, as does “O” and “X.” But N, S, and Z don’t have reflectional symmetry at all! And they DO have rotational symmetry. O,T,U V,W,X, and Y.ĭoes the letter H have reflection symmetry? What letters of the English alphabet have reflectional symmetry (i.e., symmetry related to mirror reflection) about. ![]() What capital letters look the same in the mirror?Ĭapital English alphabet has 11 symmetric letters that appear same when looked at in a mirror.
