It is not vital that every the figurespossess a heat or present of the contrary in various figures.

You are watching: How many lines of symmetry in a triangle

Figures may have:

No heat of symmetry

1, 2, 3, 4 …… present of symmetry

Infinite currently of symmetry


Let us take into consideration a list of examples and also findout lines of symmetry in various figures:

1. Line segment:


*

In the figure there is one line of symmetry.The number is symmetric follow me the perpendicular bisector l.

2. One angle:


*

In the figure there is one heat of symmetry.The number is symmetric follow me the angle bisector OC.

3. An isosceles triangle:


*

In the number there is one line of symmetry.The number is symmetric follow me the bisector of the upright angle. The typical XL.

4. Semi-circle:


*

In the number there is one line of symmetry.The figure is symmetric along the perpendicular bisector l. That the diameter XY.

5. Kite:


*

In the number there is one line of symmetry.The number is symmetric along the diagonal line QS.

6. Isosceles trapezium:


In the number there is one heat of symmetry.The number is symmetric along the heat l joining the midpoints of 2 parallel sides abdominal muscle and DC.

7.Rectangle:


In the figure there are two present ofsymmetry. The figure is symmetric along the lines l and m joining the midpoints ofopposite sides.

8. Rhombus:


In the number there are two currently of symmetry.The number is symmetric follow me the diagonals AC and BD that the figure.

9. It is provided triangle:


In the figure there space three lines of symmetry.The figure is symmetric follow me the 3 medians PU, QT and RS.

10. Square:


In the number there are four lines ofsymmetry. The number is symmetric follow me the 2diagonals and also 2 midpoints ofopposite sides.

11. Circle:


In the figure there are unlimited lines ofsymmetry. The figure is symmetric along all the diameters.

Note:

Each continual polygon (equilateral triangle,square, rhombus, consistent pentagon, continual hexagon etc.) are symmetry.

The number of lines of the contrary in a regularpolygon is same to the number of sides a continuous polygon has.

Some figures like scalene triangle andparallelogram have actually no currently of symmetry.

Lines of symmetry in letter of the English alphabet:

Letters having actually one line of symmetry:

A B C D E K M T U V W Y have one heat of symmetry.

A M T U V W Y have actually vertical heat of symmetry.

B C D E K have actually horizontal line of symmetry.


Letter having both horizontal and also vertical lines of symmetry:

H ns X have two lines of symmetry.


Letter having actually no lines of symmetry:

F G J l N ns Q R S Z have neither horizontal nor vertical lines of symmetry.


Letters having infinite lines of symmetry:

O has infinite currently of symmetry. Infinite variety of lines passes v the allude symmetry around the center O with all feasible diameters.
