    Answer

    1. A
      Solution:
      A triangle can have two or even all three acute angles (in case of an equilateral triangle) but it cannot have two right angles or two obtuse angles as the sum of the interior angles of a triangle is 180º and two right angles or two obtuse angles would sum up to 180º or more leaving the no space for the third angle.
