74 sides
What is the study of heptagons if trigonometry is the study of triangles?
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.
Are all the sides of a octahedron equilateral triangles?
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.
How many triangles in a triacontakaidigon?
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.
How many sides in all triangles?
Three
What shape have no pairs of parallel lines?
