The measure of one of the exterior angles of a triangle is twice one of the interior opposite angles and the measure of the other interior opposite angles is 60$$^\circ$$. The triangle is a/an:
Given, two interior angles of the triangle is 60$$^\circ$$.
$$\Rightarrow$$ The third interior angle must be 60$$^\circ$$ as the sum of the interior angles is 180$$^\circ$$.
$$\therefore$$The triangle is an equilateral triangle.
Hence, the correct answer is Option A
