Which 2D shapes have lines of symmetry?
A 2D object or shape can be said to be symmetrical if a line can be drawn through the middle so that the two halves are mirror images of each other. The line drawn through the middle is called the line of symmetry. 2D shapes like squares have four lines of symmetry and rectangles have two lines of symmetry.
What 2D shape has 4 lines of symmetry?
square
An square has 4 lines of symmetry. An regular hexagon has 6 lines of symmetry. An regular octagon has 8 lines of symmetry. Regular shapes have the same number of lines of symmetry as they do sides!
What are lines of symmetry in shapes?
A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly. Equally, if you were to place a mirror along the line, the shape would remain unchanged. A square has 4 lines of symmetry, as shown below.
What 2D shape has 5 lines of symmetry?
regular pentagon
A regular pentagon has 5 sides and 5 lines of symmetry. The number of lines of symmetry in a regular polygon is equal to the number of sides.
Which shape has no lines of symmetry?
Summary: A scalene triangle, parallelogram, and a trapezium are three examples of shapes with no line of symmetry.
How many lines of symmetry are there?
The lines or axes may be any combination of vertical, horizontal and diagonal. But basically there are two types of lines of symmetry, they are: Vertical Line of Symmetry. Horizontal Line of Symmetry.

Does a square have 2 lines of symmetry?
For the square, it can be folded in half over either diagonal, the horizontal segment which cuts the square in half, or the vertical segment which cuts the square in half. So the square has four lines of symmetry.
How many lines of symmetry does Oval have?
2 lines of symmetry
an oval have? The oval is symmetrical because when I draw a line through the middle it looks exactly the same! The oval has 2 lines of symmetry because it looks exactly the same!
What are the 4 types of symmetry?
Types of symmetries are rotational symmetry, reflection symmetry, translation symmetry, and glide reflection symmetry. These four types of symmetries are examples of different types of symmetry on a flat surface called planar symmetry.
Which one is example of 4 lines of symmetry?
A square
A square is symmetrical along four lines of symmetry, two along the diagonals and two along with the midpoints of the opposite sides. Some other patterns also have four 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.
How many lines of symmetry does hexagon?
6Hexagon / Line of symmetry
Which shape has 1 line of symmetry?
A semicircle has 1 line of symmetry.
Do all shapes have a line of symmetry?
Some shapes, such as a scalene triangle, have no lines of symmetry – it is not possible to fold the shape about a line so that the two halves fit exactly on top of one another.
Which shape has no line of symmetry?
A scalene triangle, a parallelogram and a trapezium do not have any line of symmetry.
What is the symmetry of circle?
infinite lines of symmetry
A circle has infinite lines of symmetry. A circle is symmetric about all its diagonals. Was this answer helpful?
Which shape has 4 lines of symmetry?
A square has four lines of symmetry.
How many lines of symmetry does a circle have?
infinite number
A circle has an infinite number of lines of symmetry since any straight line passing through the centre of the circle will be a line of symmetry.
What is the line of symmetry of a rhombus?
2Rhombus / Line of symmetry
What are the 3 basic types of symmetry?
There are three types of symmetry found in animals, radial symmetry, bilateral symmetry and asymmetrical.
What is symmetry with example?
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.
Which shape has exactly 3 lines of symmetry?
An equilateral triangle
An equilateral triangle has about three lines of symmetry. It is symmetrical along its three medians.
Which shapes have 3 or more lines of symmetry?
An equilateral triangle has three lines of symmetry. A circle has an infinite number of lines of symmetry.
How many lines of symmetry does a circle?
infinite
Since there are an infinite number of lines through the center, the circle has an infinite number of lines of symmetry. When the circle is folded over a line of symmetry, the parts of the circle on each side of the line match up. This means that the parts of the circle on each side of the line must have the same area.
