An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The faces of octahedra can be triangles, quadrilaterals, pentagons, hexagons or heptagons. There are many examples of octahedra - a hexagonal prism, for example - which has no triangular face. At the other extreme, all the faces of a regular octahedron are equilateral triangles.

An octahedron.


Are all isosceles triangles also equilateral triangles?

No, not at all, all isosceles triangles aren't equilateral since an equilateral triangle is a triangle with all of its sides equal, i.e. all sides of an equilateral triangle are equal, but in an isosceles triangle only two of its sides are equal.


Can all isosceles triangles be equilateral triangles?

No, not all isoceles triangles can be equilateral triangles because an equilateral triangle has sides that are all equal to each other and an isoceles triangle has only two sides that are equal to each other.

How many sides does an equilateral triangle have?

All triangles have exactly three sides. This is true whether the triangle is equilateral or not. If the triangle is equilateral, then the three sides will all be equal in length.All triangles have three sides.

What equilateral triangles are isosceles?

All of them are, isosceles triangles top 2 sides are equal. Equilateral triangles have 3 equal sides and satisfy the requirements of isosceles.


Are triangles equilateral?

Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.

no. if one triangles sides are all 2 and one triangles sides are all 3 then they are not congruent


All isosceles triangles are equilateral true or false?

False. TrueAn isosceles triangle has at least 2 equal sides. An equilateral triangle has 3 equal sides. Therefore all equilateral triangles are isosceles, but not all isosceles triangles are equilateral.


Are all equilateral triangles isosceles angles?

An equilateral TRIANGLE is not an isosceles ANGLE. However, all equilateral triangles are isosceles triangles. By definition, an isosceles triangle has at least two sides that are congruent. An equilateral has three sides that are congruent, thus an equilateral triangle is an isosceles triangle.


Are all equilateral triangles isosceles triangles?

No because an equilateral triangle has 3 equal sides but an isosceles triangle has only 2 equal sides
