Symmetry And Line Of Symmetry: An Introduction. In geometry, symmetry is defined as a balanced and proportionate similarity that is found in two halves of an object. It means one-half is the mirror image of the other half. The imaginary line or axis along which you can fold a figure to obtain the symmetrical halves is called the line of symmetry.

Symmetry is defined as a proportionate and balanced similarity that is found in two halves of an object, that is, one-half is the mirror image of the other half. For example, different shapes like square, rectangle, circle are symmetric along their respective lines of symmetry.
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.
Reflective symmetry. An imaginary line which splits a shape equally in two, where both sides are a reflection of each other. is an imaginary line which splits a shape equally in two. Each half ...
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.
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.

Aug 3, 2023 · A shape shows rotational symmetry when we rotate it around a central point at an angle other than 360°, and the outcome is the same as the shape’s original appearance. Reflectional Symmetry A shape has a reflectional (reflective) symmetry if the line of symmetry divides the object into two equal halves such that each half is a mirror image of the other.
