no
they are all triangles
isosceles are 45-45-90
Yes.
No. But all isosceles triangles and equilateral triangles are.
no
All isosceles triangles are not equilateral triangles
No. Only right triangles do, and not all triangles can be right triangles. Equilateral triangles, for example, are always 60°-60°-60°. Isosceles and scalene triangles can be right triangles; all isosceles triangles have the additional useful property of being able to be split into two right triangles.
The right isosceles triangle has 180 degrees as all triangles do
All isosceles triangles are not equilateral triangles
An isosceles triangle may have a right angle, but a right angle is not a requirement of all isosceles triangles.
It can only have a maximum of one- and that is only if it is a right-angled isosceles triangle. ----------------------------------------------------- Yes not all isosceles triangles are right angle triangles - this is a special case.

they are all triangles
isosceles are 45-45-90
Yes.
No because 30-60-90 triangles are right angle triangles
