Triangle/Line of symmetry.
How many lines of symmetry does a triangle have?
An equilateral triangle has three lines of symmetry. It has rotational symmetry of order 3.
How many lines of symmetry a triangle does not have?
A triangle cannot have more than 3 lines if symmetry.
What is the symmetry of a triangle?
Triangles Equilateral Triangle (all sides equal, all angles equal) Isosceles Triangle (two sides equal, two angles equal) Scalene Triangle (no sides equal, no angles equal) 3 Lines of Symmetry 1 Line of Symmetry No Lines of Symmetry.
Can a triangle have 2 lines of symmetry?
2. Few shapes or figures have one line of symmetry, two lines of symmetry or multiple lines of symmetry. The equilateral triangle has three lines of symmetry whereas a scalene triangle does not have any line of symmetry as its all sides are different.
How many lines of symmetry isosceles triangle have?
1
Which triangle has two lines of symmetry?
No triangle has 2 lines of symmetry. Equilateral triangle has three lines of symmetry while an isosceles has one. A scalene triangle has none.
How many lines of symmetry are there in the following figure?
Answer: (a) There are 4 lines of symmetry for the given figure.
How do you find the symmetry of a triangle?
The two sides meeting at that vertex must be the same length in order for there to be a line of symmetry. When the two sides meeting at a vertex do have the same length, the line of symmetry through that vertex passes through the midpoint of the opposite side.
How do I find the line of symmetry?
To find the line of symmetry algebraically, you need to identify if the equation is written in standard form or vertex form. Standard form is y = ax^2 + bx + c, where a, b, and c equal all real numbers. You can use the formula x = -b / 2a to find the line of symmetry.
How do you find a line of symmetry?
To find a line of symmetry, look for two halves of the shape that are mirror images of each other. The bottom half of the shape is the mirror image of the top half. So, the horizontal line that passes through the middle is a line of symmetry.
What shape has no line of symmetry?
A scalene triangle – A scalene triangle has no line symmetry because it has all sides unequal in length. A parallelogram – A parallelogram has opposite sides equal and parallel but a parallelogram has no line of symmetry. A trapezium – In a trapezium, only two opposite sides are parallel to each other.
What shapes have exactly 4 lines of symmetry?
Square. A square has four lines of symmetry. It has rotational symmetry of order four.
What shape has 4 sides and 1 line of symmetry?
Kite. A kite is a quadrilateral with one axis of line symmetry.
How many lines are in a triangle?
Loh: “A triangle is made of three lines.
How many lines does a triangle have?
A triangle is composed of three line segments. The line segments intersect in their endpoints. To name a triangle we often use its vertices (the name of the endpoints). The triangle below is named ABC.
What is 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.
Which triangle has horizontal line of symmetry?
(a) The figure shows an isosceles triangle with a horizontal line of symmetry but no vertical line of symmetry. (b) Rectangle (quadrilateral) shows both the horizontal and vertical lines of symmetry.
How many lines of symmetry has a square?

Did triangles have line symmetry?
The dashed lines represent lines of symmetry, and each shape is said to be symmetrical about this line. 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.
How many lines of symmetry are there in a triangle with all sides of equal length?
An equilateral triangle, or a triangle in which all of the sides have equal length, has three lines of symmetry.
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.
How many lines of symmetry does the alphabet have?
That’s right! 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.
How many lines of symmetry does a hexagon have?
6
What shape has 8 vertices and no lines of symmetry?
Octagon Regular octagon Type Regular polygon Edges and vertices 8 Schläfli symbol {8}, t{4} Coxeter diagram.
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.
How many triangles are there in a big triangle?
The drawing was shared on Quora earlier this month and has people scratching their heads. Most people on Quora unanimously agreed that the answer is 24, with each row containing six triangles.
What do the lines in 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. An equilateral triangle has 3 sides of equal length. The dashes on the lines show they are equal in length. All of the angles are also equal.
Can you draw a triangle which has exactly one line of symmetry?
(a) Yes. An isosceles triangle can be drawn that has only 1 line of symmetry.
What is the line in the middle of a triangle called?
In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle’s centroid.
How many lines does a hexagon have?
The six lines of reflection of a regular hexagon, with Dih6 or r12 symmetry, order 12.
Is a triangle horizontal?
Triangles can be best described as horizontal trading patterns. At the start of its formation, the triangle is at its widest point.
