4 Draw a line from each vertex through the center and check for line symmetry. 5 State the number of lines of symmetry. The equilateral triangle has 3 3 lines of symmetry. An equilateral triangle has 3 3 equal sides and 3 3 equal angles, so it will have 3 3 lines of symmetry.

In Mathematics, a meaning of symmetry defines that one shape is exactly like the other shape when it is moved, rotated, or flipped. Consider an example, when you are told to cut out a ‘heart’ from a piece of paper, don’t you simply fold the paper, draw one-half of the heart at the fold and cut it out to find that the other half exactly matches the ...
The imaginary line or axis along which you fold a figure to obtain the symmetrical halves is called the line of symmetry. It basically divides an object into two mirror-image halves. The line of symmetry can be vertical, horizontal or diagonal. There may be one or more lines of symmetry.
Symmetry may be viewed when you flip, slide or turn an object. There are four types of symmetry that can be observed in various situations, they are: 1. Translation Symmetry 2. Rotational Symmetry 3. Reflection Symmetry 4. Glide Symmetry
The symmetry of shapes can be identified whether it is a line of symmetry, reflection or rotational based on the appearance of the shape. The shapes can be regular or irregular. Based on their regularity, the shapes can have symmetry in different ways. Also, it is possible that some shapes does not have symmetry. For example, a tree may or may not ...

Symmetry Examples. Example 1: If the following figure shows a reflexive line of symmetry, complete the figure. Solution: It is given that the figure has a reflexive line of symmetry. That means the second half or the missing part of the figure will be exactly the same as given on the other side.
Example 3: using angles. Show that the hexagon below has no lines of symmetry. Locate the centre of the 2D shape. Show step. Draw a small x x in the centre of the hexagon (this does not have to be exact): Use a ruler to visualise a horizontal and/or vertical line of symmetry through the centre of the shape. Show step.
So this is not a Line of Symmetry. But when I try it this way, it does work (the folded part sits perfectly on top, all edges matching): So this is a Line of Symmetry. Triangles. A Triangle can have 3, or 1 or no lines of symmetry:
a rigid transformation that moves an object back onto itself. There are two types of such symmetries: reflectional symmetry and rotational symmetry. Reflectional Symmetry or Line Symmetry. Basically, a line of symmetry is a line that divides a figure through its center. into two mirror images.

What are regular polygons?
A regular polygon is a convex polygon whose angles are all congruent and whose sides are all congruent. The regular polygons with three and four sides have the special names equilateral triangle and square, respectively. Otherwise, they are simply called regular pentagon, regular hexagon, etc., regular n -gon.
