# What are the names of polygons which are equilateral but not regular?

They would be equilateral concave polygons. See the related link to see some diagrams.

### What are regular polygons?

Regular polygons are those polygons that are both equilateral (all sides congruent) and equilateral (all interior angles congruent).

### What polygon is both equiangular and equilateral?

There are many polygons that are both equiangular and equilateral. For example, squares and equilateral triangles are both equiangular and equilateral polygons. The general term for polygons that are both equiangular and equilateral is regular.

### Is it true that regular polygons are both equilateral and equiangular?

Yes, regular polygons have equal side lengths and equal interior angles as for example an equilateral triangle or maybe a square.

### What shape has all equal sides?

An equilateral polygon. All regular polygons, being equilateral, will have equal sides but it is not necessary that they are regular. A rhombus, for example, is equilateral but not regular.

### Which regular polygons will not tile a surface?

An [equilateral] triangle, square and hexagon are the only regular polygons which, by themselves, will tile a surface.

### What does a square and an equilateral triangle have in common?

They are both regular polygons.

### What is a polygon with all sides and the same length and all angles the same measure is called?

A regular polygon. Equilateral triangle and square are examples of regular polygons (those two have special names).

### Is a triangle a small regular polygon?

A regular polygon is any polygon that has sides which are the same length and angles whose measures are equal. An equilateral triangle (also equiangular triangle) is a regular polygon. Other isosceles triangles (equilateral triangles are isosceles, but they are an exception) and scalene triangles are not regular polygons. A side note: Only in a triangle is a polygon regular solely if it is equilateral. (Since an equilateral triangle is equiangular as well). This is… Read More

### Do regular polygons tessellate?

Any polygon with external angles which are equal to a factor of 360 will tessellate. The only regular polygons which will tessellate are equilateral triangles, squares, and hexagons.

### What does an obtuse equilateral look like?

There cannot be an obtuse equilateral triangle. A rhombus is an equilateral quadrilateral with two obtuse angles (and two acute ones). Not sure if that counts as an obtuse equilateral. All regular polygons with more than four sides will be obtuse and equilateral. There are also other polygons that will meet these requirements. These will be squashed polygons in the same way that a rhombus is a squashed square.

### What does the word equilateral mean?

an equilateral triangle is a triangle in which all three sides are equal. Equilateral means that all the sides in a figure are congruent. Regular polygons are all equilateral.

### How can you tell if a regular shape will tessellate?

It will tessellate if its vertices divide into 360 degrees evenly. The only regular polygons that will tessellate are an equilateral triangle, a square and a regular hexagon. There are other, non-regular, polygons that will tessellate.

### What regular polygons can be used to form a tessellation?

Polygons whose vertices are factors of 360 degrees such as a square or an equilateral triangle ... etc

### What regular polygons tessellate on their own without any spaces or overlaps?

Equilateral triangle, square and regular hexagon.

### Which of the polygon appear to be regular?

Polgons that have equal sides and equal angles are regular polygons such as a square or an equilateral triangle

### Are all equiangular polygons also equilateral?

Yes in general polygons that have equal interior angles also have equal sides and they are said to be regular polygons. But a rectangle is an exception.

### Which geometric figure has all sides congruent?

They are regular polygons as for example an equilateral triangle

### What are the three type of polygons that can be a platonic solid?

Equilateral triangles, squares, regular pentagons.

### A polygon with equal sides and equal angles?

They are regular polygons such as a square and an equilateral triangle

### What shape has congruent angles?

Regular polygons have congruent angles such as squares and equilateral triangles.

### Which ragular polygons can tessellate a plane with no overlaps or gaps?

Equilateral triangle, square and regular hexagon.

### Which shapes have all sides equal?

All regular polygons. But there are also others which look like squashed versions of regular polygons. A "squashed" square makes a rhombus. Similarly there are squashed polygons with larger numbers of sides. They should be called equilateral polygons, but that phrase is not much used.

### What to regular polygons has a larger exterior angle?

An equilateral triangle is the only polygon in which the exterior angle is larger than the interior angle. They are equal in a square and smaller in all regular polygons with more sides,

### Which shapes have eqaul sides?

All regular polygons, from an equilateral triangle upwards. Aslo, all regular polygons with 4 or more sides can be squashed or distorted but they would still have sides of equal length.

### What shape has a rotational symmetry of 120 degree?

An equilateral triangle, and all regular polygons with 3n sides.

### Are the triangles in a geodesic dome regular polygons?

Only if it is a regular tetrahedron, regular octahedron, or regular icosahedron. All other geodesics have isosceles triangle faces, not equilateral triangles.

### Is regular polygons also similar?

-- All regular (equilateral) triangles are similar. -- All squares are similar. -- All pentagons are similar. -- All hexagons are similar. . . . etc. Any regular polygon is similar to all other regular polygons with the same number of sides.

### Is a kite a regular polygon?

The definition of a regular polygons is a polygon that is both equiangular and equilateral. in a kite not all the sides are the same then its angles are not all equal then it is not a regular polygon.

### What polygon has sides that are all the same length?

The polygon, as described in the question, is an equilateral polygon. If, in addition to this, all its angles have the same measure then the polygon is said to be regular. Polygons can be equilateral or equiangular or both (regular). The one exception is a triangle where equilateral implies (and is implied by) equiangular.

### Can only regular polygons with an even number of sides make a regular tessellation?

No. Equilateral triangles will tessellate and a triangle has 3 sides, which is an odd number.

### Which of these two regular polygons has the largest exterior angle heptagon or triangle .?

It is the regular equilateral triangle whose each exterior angle is 120 degrees

### What shapes has equal sides?

Equilateral shapes. They can be polygons with any number of sides and, apart from a triangle, they need not be regular.

### Can all regular polygons tessellate?

No only three can tesselate. they are: An equilateral triangle, a square and a 6 sided hexagon.

### What regular polygons will tesellate on their own?

Hexagon, square, equilateral triangle, octagon. Im 11 so hah

### What regular polygons can be tessellated?

In a normal plane, only regular polygons with interior angles that are a factor of 360o can be tessellated. This means only three shapes: the regular (equilateral) triangle, the regular quadrilateral (square) and the regular hexagon. If the line were considered a regular polygon (with only two sides) then it would also be included in this list.

### What is a equilateral polygon?

In geometry, an equilateral polygon is a polygon which has all sides of the same length. For instance, an equilateral triangle is a triangle of equal edge lengths. All equilateral triangles are similar to each other, and have 60 degree internal angles. : Any equilateral quadrilateral is a rhombus, which includes the square. : An equilateral polygon which is cyclic (its vertices are on a circle) is a regular polygon. Not all equilateral polygons are… Read More

### What are angles segments triangles etc that have exactly the same measures?

They are said to be regular polygons such as equilateral triangles, squares and other polygons that have congruent sides and equal congruent interior angles.

### Which polygons will tile the plane?

If it's interior angle is a factor of 360 then it will tessellate such as a square, a regular hexagon and an equilateral triangle.

### What is a Polygon that is both equiangular and equilateral?

A rhombus if i remember my geometry its a rhombus A rhombus is NOT equiangular. A square is the only quadrilateral with equal sides and equal angles. An equilateral triangle is also equiangular. Polygons that are equilateral and equiangular are called regular.

### Which of these two regular polygons has the larger exterior angle a triangle or a heptagon?

It is the equilateral triangle that has the largest exterior angle of 120 degrees

### How many congruent sides does an equilateral have?

Equilateral triangles have 3 congruent(equal) sides and 3 congruent angles, because equilateral means that all the sides are equal. If a polygon(shape with 3 + sides) is equilateral and equiangular( all the angles are the same), then it is regular. Some equiangular polygons are not equilateral, and vice versa.

### How do you find the Perimeter of a polygon with only the area?

Different polygons have different relationships between perimeter and area. For example, if we assume regular polygons, an equilateral triangle and a square have different perimeters for the same area. If you allow irregular polygons, the variety is even bigger.
