Class 9Linear Pair and Vertically Opposite AnglesGeometry — Lines and Angles
  • AYes, always
  • BNo, their sum would be less than 180°
  • CYes, if each is 80°
  • DOnly if one is a right angle

Step-by-Step Solution

Two acute angles are each below 90°, so their sum is below 180° and cannot equal 180. So both cannot be acute.
Answer: B) No, their sum would be less than 180°
