A triangle has 3 lines of symmetry.

Number of lines of symmetry = Number of sides of the regular polygon

A regular triangle (aka equilateral triangle) has three lines of symmetry - these are its medians, In general, a regular n-gon has n lines of symmetry.

10 lines. Regular polygon of "x" sides has "x" Lines of Symmetry

it depends on what kind of shape it is. an equilateral triangle has 3 lines of symmetry, yet a sqaure has 4. (both shapes i mentioned are regular polygons)

A square has four lines of symmetry!

It has 16 lines of symmetry.

It depends on how many sides that it has and whether of not it is regular (all the lines of the polygon are of equal length if it is a regular polygon). For regular polygons, the number of symmetry lines is the number of sides if number of sides is an odd number. Otherwise, the number of symmetry lines is double the number of sides. A square has 4 sides and 8 symmetry lines; a triangle has 3 sides and 3 symmetry lines.

It has 32 lines of symmetry.

A regular five sided pentagon has 5 lines of symmetry.

Regular pentagon

a regular square

Yes, for example, an equilateral triangle.

How many lines of symmetry does the 15 side polygon have

A regular Undegon (11 sided polygon) has 11 lines of symmetry. It also has an order of rotation symmetry of 11.

A regular 24 sided polygon has 24 lines of symmetry.

A polygon need not have any lines of symmetry. The maximum number of lines of symmetry is attained if the polygon is regular; and this is the number of sides (or vertices) of the polygon. If a regular polygon has an even number of sides, then the lines of symmetry are those joining opposite vertices, and those joining the mid-points of opposite sides. If the polygon has an odd number of sides/vertices, the lines of symmetry are those joining each vertex to the mid-point of the opposite side.

It will have 22 lines of symmetry

Yes. A triangle only has three.
