Are some right triangles have equilateral triangles?

No. For it to be equilateral it can't be a right triangle.


Are some right triangles are also equilateral triangles?

No because all right triangles have 2 legs and a hypotenuse. The hypotenuse is always longer than either leg so right triangles can't be equilateral triangles.


Is a scalene triangle an equilateral triangle?

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.


What are some triangles?

isocles, equilateral, obtuse, acute, scalene, right


What are the plationic solids?

Platonic solids are convex regular (equiangular) polyhedra. There are five Platonic solids: the tetrahedron, or pyramid (four equilateral triangles for faces; traditionally associated with the element Fire), the octahedron (eight equilateral triangles; traditionally associated with Air), the icosahedron (twenty equilateral triangles; traditionally associated with Water), the cube (six squares for faces; traditionally associated with Earth), and the dodecahedron (which has twelve regular pentagons for faces and is associated with the legendary Luminiferous Aether that had often been considered an element). These are the only existing regular polyhedra that exhibit convexity; other, non-convex regular polyhedra (meaning that there are angles between some of their faces that are less than 180 degrees as measured from the outside surface) exist and are known as star polyhedra.

Dodecahedron has triangular faces?

A dodecahedron is a polyhedron with 12 faces. There are 6,384,634 topologically distinct convex dodecahedra with 8 or more vertices. A hexagonal bipyramid, a dodecadeltahedron, a triakis tetrahedron are examples of dodecahedra all of whose faces are triangles. There are many more dodecahedra in which some, but not all, faces are triangles.


Does a musical triangle have to be equilateral?

No, some early musical triangles were isosceles triangles, most modern musical triangles are equilateral.


Are some equilateral triangles scalene?

No, a scalene is a scalene and an equilateral is an equilateral. They are NOT the same.


Are some right triangles also the same as equilateral triangles?

No...


Are triangles equilateral?

Triangles can be classified into different shapes. Equilateral ; All sides the same length ; all angles equal 60 degrees. Isosceles ; Two sides the same length ; two angles equal size. Right-Angled ; Three sides can be of different lengths ; MUST have one right-angle. Scalene ; All sides of different lengths ; all angles of different size. Common 2-dimensioanal characteristics for ALL triangles. ; - They contain three(3) sides They contain three(angles) The internal angles ALWAYS sum to 180 degrees. A triangle may also be named a TRIGON ; A polygon of three sides. NB Triangles drawn on a 3-dimensional surface ( sphere ), the above characteristics can vary.


Are some right triangles also equilateral triangles?

no because an equilateral triangle has 3 sides that have equal angles and is not 90 degrees


Are some right triangles are also equilateral triangles?

No because all right triangles have 2 legs and a hypotenuse. The hypotenuse is always longer than either leg so right triangles can't be equilateral triangles.
