What else can I help you with?
An equilateral triangle has reflectional symmetry but does not have rotational symmetry?
It does have rotational symmetry of order three.
Is it true Only regular polygons with an even number of sides are symmetrical?
No, it's not true that only regular polygons with an even number of sides are symmetrical. Regular polygons, regardless of whether they have an even or odd number of sides, are symmetrical. They possess rotational symmetry and reflectional symmetry; for example, a regular triangle (3 sides) and a regular pentagon (5 sides) both exhibit symmetry.
Does a regular triangle have a reflectional symmetry?
yes it does put the mirror in the middle of the midpoint and vertex
Does a right triangle have reflectional symmetry?
yes because if u put it by a mirror u look at that by yourself
What is the kinds of polygons?
Triangle, quadrilateral, Pentagon, hexagon, heptagon, octagon, nonagon, decagon, undecagon, and dodecagon

Describe the symmetry of an equilateral triangle?
an equilateral triangle has both reflectional and rotational symmetry. hope this helped:)
What are three polygons?
Triangle, octagon, and my favorite, dodecagon.

Does a regular triangle have a reflectional symmetry?
yes it does put the mirror in the middle of the midpoint and vertex
Does a triangle have reflectional symmetry?
yes because you can fold it in half and it will be exactly the same on either side.
What is a list of polygons?
A list of polygons would include the triangle, quadrilateral, pentagon, octagon, and the hexagon. Some additional polygons are the enneagon, the heptagon, the dodecagon, and the hexdecagon.
Does a right triangle have reflectional symmetry?
yes because if u put it by a mirror u look at that by yourself
What is the kinds of polygons?
Triangle, quadrilateral, Pentagon, hexagon, heptagon, octagon, nonagon, decagon, undecagon, and dodecagon
What is the three polygons that have lines of symmetry?
Rectangle, and equilateral/icoscles triangle, and a pentagon
Which US state flags contain symmetry?
US State flags with reflectional symmetry are:AlabamaArizonaColoradoNew MexicoThe flag of Maryland appears to have rotational symmetry at first glance, but in fact the colours are rotated in each canton (corner).Similarly, Ohio's flag appears to have reflectional symmetry, but the stars in the flag are rotated in the bottom half of the triangle on the left-hand side.
What shape has a rotational symmetry of 120 degree?
An equilateral triangle, and all regular polygons with 3n sides.
