An isosceles triangle has one line of symmetry as both of its sides are equal. ... These shapes are said to have Two Lines of Symmetry. The rectangle is an example of Two Line of Symmetry. A Rectangle can be divided vertically, horizontal or diagonally to get the two symmetrical parts.
Which shapes have 2 or more lines of symmetry?
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 has exactly two lines of symmetry?
A rectangle has two lines of symmetry. It has rotational symmetry of order two.
How many lines of symmetry does a have?
The F and G have zero lines of symmetry. Those letters cannot be folded in half in any way with the parts matching up. The rest of the letters, A, B, C, D, and E all have only 1 line of symmetry. Notice that the A has a vertical line of symmetry, while the B, C, D, and E have a horizontal line of symmetry.
What shape has no lines of symmetry?
Two shapes that have no lines of symmetry are the scalene triangle and an irregular quadrilateral.

What are examples of lines of symmetry?
For example, take your face. When we draw a line down our face exactly at the centre, then the left side of our face is symmetric to our right side of the face. This defines symmetry. This line that divides a figure or shape or any image in identical halves then that figure is said to have a line symmetry.
What is not a line of symmetry?
Basically, a line of symmetry is a line that divides a figure into two mirror images. ... But the diagonal line is NOT a line of symmetry. Folding along the diagonal does not coincide with the other side. The diagonal of a parallelogram also divides the figure into two triangles that are congruent.
Which figure has line symmetry?
Letters like B and D have a horizontal line of symmetry: their top and bottom parts match. Some letters, for example, X, H, and O, have both vertical and horizontal lines of symmetry. And some, like P, R, and N, have no lines of symmetry.
What is a symmetry line?
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 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 figure has 3 lines of symmetry?
An equilateral triangle has three lines of symmetry. It has rotational symmetry of order 3. It has three equal sides.
What is symmetry with example?
Symmetry is an attribute where something is the same on both sides of an axis. An example of symmetry is a circle that is the same on both sides if you fold it along its diameter.
Does a circle have lines of symmetry?
Since there are an infinite number of lines through the center, the circle has an infinite number of lines of symmetry. ... So a line of symmetry divides the circle into two parts with equal area.
Are Quadrilaterals symmetrical?
So the square has four lines of symmetry. ... One way to show this is to note that for a quadrilateral, a line of symmetry must either match two vertices on one side of the line with two vertices on the other or it must pass through two of the vertices and then the other two vertices pair up when folded over the line.
How many lines of symmetry does a oval have?
In general, an ellipse has two lines of symmetry.
Which shape has exactly 4 lines of symmetry?
A square is a regular polygon . It has four lines of symmetry and four sides.
What are the 5 types of symmetry?
There are five types of symmetry operations including identity, reflection, inversion, proper rotation, and improper rotation.
Which is a symmetry?
Something is symmetrical when it is the same on both sides. A shape has symmetry if a central dividing line (a mirror line) can be drawn on it, to show that both sides of the shape are exactly the same.
What is symmetry shape?
Symmetry. A 2D shape is symmetrical if a line can be drawn through it and either side is a reflection of the other. The line is called a line of symmetry. This is sometimes called a 'mirror line' or 'mirror symmetry', because if you put a mirror on the line, the reflection would show the whole shape.
How many lines of symmetry are there in the following figure T?
There is only one line of symmetry in T.
A line of symmetry is that line which divides the figure in such a way, that the two parts are a mirror image of each other.
What is symmetry and patterns?
Symmetrical patterns are a design or pattern that is identical on both halves when folded. Symmetrical patterns can have multiple lines of symmetry. To find a line of symmetry you can fold a shape.
Where is symmetry found?
Symmetrical forms can be found in the inanimate world as well. The planets, with slight variation due to chance, exhibit radial symmetry. Snowflakes also provide an example of radial symmetry. All snowflakes show a hexagonal symmetry around an axis that runs perpendicular to their face.
