If it has 2 equal acute angles and 1 obtuse angle then it is an isosceles triangle.

It can be but does not have to be.

An Isosceles triangle has 2 or 3 acute angles.

Answer: Yes, because of the two angles have to be exactly equal in order to be isosceles. And no isosceles has 3 acute angles and then it will be equilateral triangle Answer: No, the isosceles triangle can either have two acute angles, or all three can be acute.

It doesn't matter if a triangle is isosceles, scalene, obtuse, acute... There are always 3 angles in a triangle (which add up to 180).

Yes

Yes, it can.

Yes, that's possible. For instance a triangle with the angles 70°, 70° and 40° is both acute and isosceles.
