Are isosceles triangle sometimes an equilateral triangle

An obtuse triangle is not necessarily isosceles, but it can be.

No. An isosceles right triangle is a special case. There are many right triangles which are not isosceles.

-- An isosceles triangle has two equal sides. -- An isosceles triangle has two equal angles. -- An isosceles triangle has two equal interior-angle bisectors. -- The bisector of the vertex angle of an isosceles triangle is also the perpendicular bisector of the triangle's base.

Usually, solid shapes have more than two faces; if that is the case, then the simplest shape we are looking at is a triangular pyramid (both upright and oblique pyramids are considered here). However, if you're looking for a two-faced solid, then you'll be fresh out of luck, even with non-Euclidean geometry, as you cannot have an equilateral triangle and an isosceles triangle in the same shape (unless you make the isosceles triangle an equilateral one).

A right triangle and an isosceles triangle have the fact that they are both triangles in common. A right triangle can also be an isosceles triangle.

You cannot. An isosceles triangle cannot be scalene and a scalene triangle cannot be isosceles. So an isosceles scalene triangle cannot exist.

Isosceles TetrahedronA solid with four faces is a tetrahedron. Each of the faces is a triangle. If all the triangles are congruent, you have an isosceles tetrahedron.
