If two angles are acute, then they are supplementary. FALSE

Example:
We have ∠A = 25°
               ∠B = 63°

Then, 
               ∠A + ∠B = 25° + 63° = 88° 

Now, we know supplementary angles are the angles that add up to 180°. But in this case, the two ACUTE angles don't add up to 180°. So, this supports that the statement above is false!

Sometimes true. It is true unless both the angles are right angles.
