Polygon means many sides. Octagon mean eight sides. Not all polygons are octagons, but all octagons are polygons. Examples of other polygons are triangles, squares, parallelograms, rhombuses, pentagons, hexagons, heptagons, decagons

74 sides

Geometry is the study of all shapes. This includes heptagons. Trigonometry developed much later than geometry for applying the study of triangles to practical application.

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.

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

A triacontakaidigon is a polyhedron with 32 sides. If the sides are all triangles, then there are 32 triangles in a triacontakaidigon, but a triacontakaidigon does not need to have triangular shaped sides.

Like all triangles it has 3 sides

no. Equilateral triangles have all equal sides. Isoceles triangles only have 2 congruent sides. Isosceles triangles have 2 equal sides.

All triangles have exactly 3 sides. That is what the word triangle means, a geometrical figure having 3 angles and 3 sides. Always 3.

All triangles have three sides. No matter what kind they are.

All triangles have three sides. Whether or not it is equilateral is irrelevant.

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.

None because all triangles have 3 sides

In 2 dimensions, triangles and all polygons with 5 or more sides (pentagons, hexagons, heptagons etc); also, circles, ellipses, cycloids, irregular shapes. Also all 3-dimensional shapes and, for the pure mathematician, any shape in more than 3 dimensions. quadrilateral's are 4 sided 2-dimensional shapes xxx

An octohedron has eight faces, all of which are triangles.
