A polyhedron is a solid shape with four or more polygonal faces. A hexahedron is a solid shape with six polygonal faces and so is a particular type of polyhedron.
Equilateral triangles.
One with 20 polygonal faces.
Equilateral triangles have rotational symmetry.
An octagonal cupola is a type of polyhedron. Faces: 18 Edges: 40 Vertices: 24 The octagonal cupola is composed of one octagon, one hexadecagon, eight rectangles, and eight triangles.
technically, triangle classes have a bulls-eye type name graph, with equilateral triangles in the middle, then isosceles, then scalene, so technically, some scalene triangles are isosceles and some are equilateral, but not all are.
There are two types of quadrilaterals that are formed when two congruent equilateral triangles are joined. These shapes are rhombus and parallelogram.
