A. A triangle can be drawn with exactly one acute angle. (False)

Explanation: In a triangle, there are three angles. It is not possible for a triangle to have only one acute angle because the sum of the interior angles in a triangle is always 180 degrees. This means that the other two angles must be either acute or obtuse to total 180 degrees.
