Not enough information has been given to find the measure of the 3rd side of the triangle ABC but if it is in the form of an isosceles triangle then the 3rd side would work out as 6 units.
30 degrees
Are you talking about the angle A. If you are then at what point of the triangle is the angle A.
It is isosceles.
It is isosceles.
Triangle ABC would be an isosceles. An isosceles triangle is defined as having two sides of equal length. This would also mean, then, that two angles in the triangle are also the same.

You must have more information about the triangle. If you know the angles, and two of them are equal, it is an isosceles triangle. If all three of the angles are sixty-degrees, it is an equilateral triangle. If none of the angles are the same, it is a scalene triangle. If one of the angles is ninety degrees, it is a right triangle (right triangles may also be scalene or isosceles). If you know the side lengths and two of them are equal, it is isosceles. If they are all equal, it is equilateral. If none of them are equal, it is scalene. A scalene or isosceles triangle may also be a right triangle, which you could determine from side lengths using the pythagorean theorem.
