Complete the following table: Shape Has line of symmetry? Number of lines of symmetry Has rotational symmetry? Order of rotational symmetry Semicircle

We know that, A figure, whose one half is exactly same shape and size as the other half, is known as symmetrical figure. Also, A line of symmetry is the line that divides an object or a shape in two identical halves. Given shape: Semicircle Given below is the diagram for Semicircle with the lines of symmetry, So we can say that the given figure has line of symmetry and the count is 1 . A rotation is a transformation in a plane that turns every point of a figure through a specified angle and direction about a fixed point. The fixed point is called the centre of rotation. The amount of rotation is called the angle of rotation and it is measured in degrees. The angle of rotational symmetry is the smallest angle for which the figure can be rotated to coincide with itself. Here the figure has rotational symmetry and the angle of rotation is 360 ° . The number of times a figure fits into itself in one complete rotation is called the order of rotational symmetry. Hence, the order of rotational symmetry is 1 . Shape Has line of symmetry? Number of lines of symmetry Has rotational symmetry? Order of rotational symmetry Semicircle Yes 1 Yes 1
