How many lines of symmetry does a regular polygon with sides have?
Line symmetry in regular polygons It has four lines of symmetry and four sides. A regular pentagon has 5 sides and 5 lines of symmetry. The number of lines of symmetry in a regular polygon is equal to the number of sides.
How many lines of symmetry are there in a regular 12 sided polygon?
twelve lines
A regular dodecagon is a figure with sides of the same length and internal angles of the same size. It has twelve lines of reflective symmetry and rotational symmetry of order 12.
How many Reflectional symmetries does a regular hexagon have?
three
A regular hexagon has a number of lines of reflection: three along the lines joining the midpoints of its opposite sides and three along the diagonals.
What is the polygon with 11 sides called?
In geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon. (The name hendecagon, from Greek hendeka “eleven” and –gon “corner”, is often preferred to the hybrid undecagon, whose first part is formed from Latin undecim “eleven”.)
How many lines of symmetry does a regular polygon have?
Regular polygon with 22 sides has 22 lines of symmetry. Step-by-step explanation: Given : regular polygon with 22 sides .
Is the number of lines of symmetry equal to its number of sides?
For any regular polygon there is a result which says that the number of lines of symmetry of a regular polygon is equal to its number of sides because:- Case 1: If the number of sides is a odd number, then there are lines of symmetry which can be create from each vertex to the midpoint of the opposite side.
What kind of symmetry does a regular hexagon have?
A regular hexagon has six rotational symmetries (rotational symmetry of order six) and six reflection symmetries (six lines of symmetry), making up the dihedral group D 6. The longest diagonals of a regular hexagon, connecting diametrically opposite vertices, are twice the length of one side.
