All triangles have three angles.
Isosceles triangles have at least 2 equal angles. The 3rd angle can either be equal to the other two (it's then called an equilateral triangle), or it can be different from the two equal angles, in which case it's an isosceles triangle. All equilateral triangles are isosceles triangles, but not all isosceles triangles are equilateral triangles.
Isosceles triangles have 2 sides that are equivalent and 2 angles that are congruent.
Yes- but not all isosceles triangles are right triangles. Isosceles means that two sides are the same length, and two angles are the same.

3 interior angles-the same as all 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're similar triangles.

Yes
all triangles have 180 degrees even isosceles
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.
Isosceles triangles have two equal sides. The angles opposite the equal sides are also equal. For instance, if the top angle is 48o and the two bottom angles are 66o an acute isosceles triangle is formed.
