Yes, by connecting the opposite vertices we can make triangles.
No because isosceles triangles always have two equal sides
If you mean an isosceles triangle then no because all triangles have no diagonals
No. An isosceles right triangle is a special case. There are many right triangles which are not isosceles.
No. For example a 3, 4, 5 cm triangle is right angled but not isosceles.

No
Yes, they are.

all triangles have 180 degrees even isosceles
No. For example a 3, 4, 5 cm triangle is right angled but not isosceles.
for a triangle to be an isosceles triangle, two of its sides and its corresponding angle must be equal. all isosceles triangles have at least one line of symmetry
Sometimes triangular prisms have isosceles triangle bases. It is the most common, but they don't always have isosceles triangles.
An isosceles triangle has at least two congruent sides. An equilateral triangle has three congruent sides. So, an equilateral triangle is a special case of isosceles triangles. Since the equilateral triangle has three congruent sides, it satisfies the conditions of isosceles triangle. So, equilateral triangles are always isosceles triangles. Source: www.icoachmath.com
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.
