A triangle is only a regular triangle in the form of an equilateral triangle
all regular triangles has 60degreeson each angles.
Only if it is a regular tetrahedron, regular octahedron, or regular icosahedron. All other geodesics have isosceles triangle faces, not equilateral triangles.
The only ones are equilateral triangles, squares and regular hexagons.
Not necessarily. If all faces are equilateral triangles (all edges are equal length) then it is a regular polyhedron.
Regular polygons such as squares and equilateral triangles
NO! Only REGULAR Pentagons. All equilateral triangles are similar!!!
you can split a regular hexagon into 6 triangles
A four faced figure is a tetrahedron. If they are all congruent triangles, they are all equilateral triangles and it is a regular tetrahedron - one of the 5 Platonic Solids.
A regular octahedron.
Octahedron- A polyhedron with eight faces. All faces of a regular octahedron are congruent, equilateral triangles.
yesthey are all regular equilateral triangles.(p.s.it is a octahedron!)
Regular polygons have all equal length sides and irregular polygons do not.
