M has one line of symmetry, and H, I, and O have 2 lines of symmetry. Did you get them all right? Do you see any lines of symmetry here? Right again! The Q, R, S are not symmetrical, so they have zero lines of symmetry. The T, U, and V are symmetrical, but they each have only one line of symmetry. None of these letters has two lines of symmetry. Now think about the last letters of the alphabet! Inspect the letters above. Do you see any lines of symmetry in any of them?
The Z is has no lines of symmetry. The W and Y have one line of symmetry. The X has two lines of symmetry. Now let's play a game with our Alphabet Symmetry. Let's review the Alphabet Symmetry with the chart above. Based on the number of lines of symmetry a letter has, that's how much the letter is "worth". Letters with zero lines of symmetry are worth zero points.
A common misconception found even in many glossaries and texts: Not all lines that divide a figure into two congruent parts are lines of symmetry. For example, the diagonal of a non-square rectangle is not a line of symmetry.
When a mirror is placed along the diagonal of a rectangle, the result does not look the same as the original rectangle, so the diagonal is not a line of symmetry. This new shape — the combination of the triangular half of the original rectangle and its image in the mirror — is called a kite. Well before children begin any formal study of symmetry, playing with mirrors — perhaps on Pattern Block designs that they build — develops experience and intuition that can serve both their geometric thinking and their artistic ideas.
The colorful design above has only vertical and horizontal lines of symmetry, but placing a mirror on it at another angle can create a beautiful new design. More intrepid experiments give other interesting results. Note that some figures, like the star and the colorful blob at the top of the page, but not the letters N, Z, or S, have both reflective and rotational symmetry. A circle has infinitely many lines of symmetry: any diameter lies on a line of symmetry through the center of the circle.
Any rotation of any amount around the center of the circle also leaves the circle unchanged. Shapes like this are called "chiral", which means that they can not be superimposed on their mirror images. Horizontal Line of Symmetry It is a sweeping line that divides the pattern into their replicating halves.
Both vertical line and horizontal line of symmetry pass through the middle of an object or alphabet or pattern to form mirror halves, which when placed on each other covers the other part. If a figure can be folded or divided into half so that the two halves match exactly then such a figure is called a symmetric figure. The figures below are symmetric.
The dotted line in each of the symmetric figures above that divides the figure into two equal halves is called the line of symmetry. And they DO have rotational symmetry. Some letters look the same when facing a mirror. Many shapes have rotational symmetry , such as rectangles, squares, circles, and all regular polygons. Choose an object and rotate it up to degrees around its center.
If at any point the object appears exactly like it did before the rotation , then the object has rotational symmetry. Answer Expert Verified In this case the upper case H.
Equilateral triangle: In the figure there are three lines of symmetry. Palindromic numbers receive most attention in the realm of recreational mathematics.
Which alphabet has line of symmetry? Category: technology and computing programming languages. In standard fonts, the letters A, M, T, U, V, W and Y each has a vertical line of symmetry that divides it into two corresponding mirror images.
B, C, D, E and K have horizontal lines of symmetry.
