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.
In the figure there is one heat of symmetry.The figure is symmetric follow me the perpendicular bisector l. The the diameter XY.
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.
In the number there are two lines ofsymmetry. The number is symmetric follow me the currently l and m joining the midpoints ofopposite sides.
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.
In the number there are 4 lines ofsymmetry. The figure is symmetric follow me the 2diagonals and 2 midpoints ofopposite sides.
In the figure there are boundless lines ofsymmetry. The number is symmetric follow me all the diameters.
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.
