What shapes has 2 lines of symmetry?
Rectangle. A rectangle has two lines of symmetry.
Which shapes can only have one line of symmetry?
A trapezium has rotational symmetry of order one. Some trapeziums have one line of symmetry. They are called isosceles trapeziums as they have 2 sides of an equal length like isosceles triangles.

What shapes has 4 lines of symmetry?
A square has four lines of symmetry.
Do all shapes have a line of symmetry?
The shapes or objects that are irregular and do not resemble each other when divided into two parts are called ASYMMETRIC. Such shapes do not have a line of symmetry. A scalene triangle, a parallelogram, and a trapezium are examples of shapes that have no lines of symmetry.
Does a shape always have one line of symmetry?
Shapes are symmetrical if they have at least one line of symmetry and circles have many, many, many lines of symmetry. There was many places we could have drawn a line and folded it so that it worked so the two halves matched exactly.
Which shape has no line of symmetry?
A scalene triangle, a parallelogram, and a trapezium do not have any line of symmetry.
What shape has unlimited lines of symmetry?
A circleA circle has an infinite number of symmetries. This contrasts with polygons such as the triangles and quadrilaterals considered in 4.
Which shape has 12 lines of symmetry?
A regular dodecagon is a figure with sides of the same length and internal angles of the same size. It has twelve lines of reflective symmetry and rotational symmetry of order 12.
Are there 5 lines of symmetry?
∴ Pentagon has 5 lines of symmetry.

What is a one line of symmetry?
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.
What is one line of symmetry called?
The imaginary line or axis along which you can fold a figure to obtain the symmetrical halves is called the line of symmetry. It is also termed as the axis of symmetry. The line symmetry is also called a mirror line because it presents two reflections of an image that coincide.
How to find the symmetry of a shape on the left?
The symmetry of the shape on the left and its relationship to the shape on the right can be thought of in two ways: Fold the left-hand shape along the central line. Then one side lies exactly on top of the other, and gives the shape on the right. Imagine a mirror placed along the central dotted line. The reflection in the mirror gives the other ...
How many lines of symmetry does a rectangle have?
A shape can have more than one line of symmetry. Thus a rectangle has two lines of symmetry, an equilateral triangle has three lines of symmetry, and a square has four. A circle has an infinite number of lines of symmetry since it can be folded about any diameter.
What is the symmetry of a mirror?
The reflection in the mirror gives the other half of the shape. This type of symmetry is called line symmetry . Any isosceles triangle has line symmetry. The dashed lines represent lines of symmetry, and each shape is said to be symmetrical about this line. The following all have line symmetry: 63. View larger image.
What are the two types of lines of symmetry?
Types of lines of symmetry is Vertical and Horizontal Symmetry.
How many lines of symmetry does 0 have?
Answer: Number 0 has 2 lines of symmetry. (1 Horizontal and 1 Vertical) Number 1 and 2 has no symmetry. Number 3 has one horizontal line of symmetry. Number 4, 5, 6 and 7 has no symmetry. Number 8 has 2 lines of symmetry. (1 Horizontal and 1 Vertical) Number 9 has no symmetry. Line of Symmetry in Geometry Shapes.
What is the horizontal line of symmetry?
Horizontal Line of Symmetry : The symmetry line or horizontal axis of a shape which divides the shape into two identical halves is known as horizontal line of symmetry
What is the axis of symmetry?
Axis of Symmetry : THe line that divides the figure into two identical parts is called A xis of Symmetry. Vertical Line of Symmetry : The axis of the shape which divides the shape into two identical halves, vertically, is called a vertical line of symmetry. Horizontal Line of Symmetry : The symmetry line or horizontal axis ...
Why does a circle have infinite symmetry lines?
ii. A circle has an infinite number of symmetry lines due to the infinite number of lines that pass through the center. This indicates that the circle’s sections on both sides of the line must be the same size. So, the other name of the line of symmetry of a circle is the diameter.
What is symmetry in architecture?
Symmetry is a concept that is frequently used in everyday life. When we encounter figures with evenly balanced proportions, we call them symmetrical. Peek at the image of the Taj Mahal and the India Gate below. Because of their symmetry, these photographs of architectural marvels are magnificent.
What is symmetry used for in painting?
Multiple lines of symmetry are used to create patterns in painting.
How many symmetry lines does a pentagon have?
Symmetry lines of a regular pentagon: All the sides of a regular pentagon are the same length and each of the measures of the angle 108 ∘. A regular pentagon has five symmetry lines.
Why is the number of lines of symmetry in a scalene triangle zero?
iii. The number of lines of symmetry in a scalene triangle is zero because it has no equal sides and angles.
