It is not necessary that every the figurespossess a heat or lines of symmetry in various figures.
You are watching: Which figure has exactly four lines of symmetry?
Figures might have:
No line of symmetry
1, 2, 3, 4 …… present of symmetry
Infinite lines of symmetry
Let us consider a list of examples and findout lines of the opposite in various figures:
1. Heat segment:
In the figure there is one line of symmetry.The number is symmetric along the perpendicular bisector l.
2. One angle:
In the number there is one heat of symmetry.The number is symmetric follow me the edge bisector OC.
3. One isosceles triangle:
In the number there is one line of symmetry.The number is symmetric along the bisector that the upright angle. The median XL.
4. Semicircle:
In the figure there is one heat of symmetry.The figure is symmetric follow me the perpendicular bisector l. The the diameter XY.
5. Kite:
In the figure there is one heat of symmetry.The figure is symmetric along the diagonal line QS.
6. Isosceles trapezium:
In the figure there is one line of symmetry.The figure is symmetric follow me the heat l joining the midpoints of 2 parallel sides abdominal muscle and DC.
7.Rectangle:
In the number there are two lines ofsymmetry. The number is symmetric follow me the currently l and m joining the midpoints ofopposite sides.
8. Rhombus:
In the number there are two lines of symmetry.The figure is symmetric along the diagonals AC and also BD the the figure.
9. Equilateral triangle:
In the number there are three lines of symmetry.The number is symmetric follow me the 3 medians PU, QT and RS.
10. Square:
In the number there are 4 lines ofsymmetry. The figure is symmetric follow me the 2diagonals and 2 midpoints ofopposite sides.
11. Circle:
In the figure there are boundless lines ofsymmetry. The number is symmetric follow me all the diameters.
Note:
Each continuous polygon (equilateral triangle,square, rhombus, regular pentagon, continual hexagon etc.) room symmetry.
The variety of lines of the contrary in a regularpolygon is same to the number of sides a regular polygon has.
Some numbers like scalene triangle andparallelogram have actually no currently of symmetry.
Lines of the contrary 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 line of symmetry.
A M T U V W Y have vertical line of symmetry.
B C D E K have horizontal line of symmetry.
Letter having actually both horizontal and also vertical present of symmetry:
H ns X have actually two currently of symmetry.
Letter having no present of symmetry:
F G J l N p Q R S Z have neither horizontal nor vertical present of symmetry.
Letters having actually infinite present of symmetry:
O has actually infinite currently of symmetry. Infinite number of lines passes through the suggest symmetry around the center O through all feasible diameters.
