What shape has exactly 4 lines of symmetry?
square
A square is a regular polygon . It has four lines of symmetry and four sides.
How many lines of symmetry does the number 9 have?
9 has no symmetry.
What shape has 9 lines of symmetry?

How many lines of symmetry does a circles have?
Since there are an infinite number of lines through the center, the circle has an infinite number of lines of symmetry.
Does a rectangle have 4 lines of symmetry?
What are Lines of Symmetry in a Rectangle? There are two lines of symmetry in a rectangle. When one line is drawn through the center along its length and the other is drawn along the width (breadth), we get the two lines of symmetry. By doing this, we get four equal and matching shapes.
What are the symmetries of a square?
The square has four lines of symmetry, indicated in gray in figure 1. There are the two axis and the two lines y = x and y = x. If we turn the square 180 about one of these lines, we get a symmetry.
What digits from 0 to 9 are symmetrical?
0, 3, 8 are the numbers which have lines of symmetry.
Which of the numbers from 2 to 9 are symmetrical?
Both 38 and 83 have a horizontal line of symmetry. We know that 83 is greater than 38. Therefore, the largest two digit number that can be formed using the digits 2 to 9, without remaining the digits, and having a horizontal line of symmetry, is 83.
What is 8 way symmetry in case of circle?
Circle is an eight-way symmetric figure. The shape of circle is the same in all quadrants. In each quadrant, there are two octants. If the calculation of the point of one octant is done, then the other seven points can be calculated easily by using the concept of eight-way symmetry.
What type of symmetry does a circle?
rotational symmetry
A circle is thus said to be symmetric under rotation or to have rotational symmetry. If the isometry is the reflection of a plane figure about a line, then the figure is said to have reflectional symmetry or line symmetry; it is also possible for a figure/object to have more than one line of symmetry.
