A line of symmetry for a triangle must go through one vertex. The two sides meeting at that vertex must be the same length in order for there to be a line of symmetry. … The triangle with side lengths 2,4,5 cannot have any lines of symmetry as the side lengths are all different.
Step-by-step explanation: No triangle has 2 lines of symmetry. Equilateral triangle has three lines of symmetry while an isosceles has one. A scalene triangle has none.
Beside this, What does 2 lines on a triangle mean?
The dashes on the lines show they are equal in length. The angles at the base of the equal sides are equal.
Likewise, Which is not a line of symmetry triangle?
scalene triangle
Also, What number has 2 lines of symmetry?
0, 3, 8 are the numbers which have lines of symmetry. A line of symmetry is a line that divides the given shape into identical parts. 0 and 8 have two lines of symmetry.
What are the 3 lines of symmetry?
An Equilateral Triangle (3 sides) has 3 Lines of Symmetry
——————————————————— —————————————————
A Square (4 sides) has 4 Lines of Symmetry
A Regular Pentagon (5 sides) has 5 Lines of Symmetry
A Regular Hexagon (6 sides) has 6 Lines of Symmetry
A Regular Heptagon (7 sides) has 7 Lines of Symmetry

What figure has 2 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. A rhombus also has two lines of symmetry. Two Lines of Symmetry can be a combination of Vertical, diagonal or Horizontal Lines.
Does a triangle have 3 lines of symmetry?
An equilateral triangle has three lines of symmetry. It has rotational symmetry of order 3. It has three equal sides.
Does O have two lines of symmetry?
J, K, L, N, and P have zero lines of symmetry. M has one line of symmetry, and H, I, and O have 2 lines of symmetry. … The Q, R, S are not symmetrical, so they have zero lines of symmetry. The T, U, and V are symmetrical, but they each have only one line of symmetry.
How many lines of symmetry a triangle has?
Does O have infinite lines of symmetry?
O has infinite lines of symmetry. Infinite number of lines passes through the point symmetry about the center O with all possible diameters.
What figure has 3 lines of symmetry?
equilateral triangle
Which shape has 2 lines of symmetry?
Rectangle
Can you draw a triangle which has two lines of symmetry?
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.
What are lines of symmetry in a triangle?
What do 2 lines on a triangle mean?
Tick marks (shown in orange) indicate sides of a shape that have equal length (sides of a shape that are congruent or that match). The single lines show that the two vertical lines are the same length while the double lines show that the two diagonal lines are the same length.
Does a triangle have more than one line 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.
Which shapes have at least 2 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.
