The question is underspecified. The answer could be an isosceles (30, 30, 120) triangle or an equilateral triangle.
A triangle is the 2D name of a certain shape. A triangle has three sides and, in the case of a right angled triangle, has an angle of 90 degrees in one corner. There are many other names depending on the angles used.
It is an obtuse triangle if its 2 other acute angles are different in sizes.
In a triangle, if all of the angles are 60 degrees, then all three sides of the triangle are equal to each other. Basically, if the angles are equal than the sides must be equal. This kind of triangle is called an equilateral triangle.
