The correct statement is: The two angles are acute.
When two angles are complementary, it means that the sum of their measures is 90 degrees. Since the two angles have the same measure, let's call this measure x.
So, the equation would be: x + x = 90.
Combining like terms, we get: 2x = 90.
Dividing both sides of the equation by 2, we find that x = 45.
Therefore, both angles have a measure of 45 degrees, which is less than 90 degrees. This means that the angles are acute.
