Vikram measures the four interior angles of a quadrilateral and gets 88°, 92°, 94° and 90°.
Which is true about his measurements?

Class 8Properties of QuadrilateralsGeometry
  • AThey are valid; the angles add to 360°
  • BThey are invalid; the angles add to 364°
  • CThey are invalid; the angles add to 360° but no quadrilateral allows them
  • DThey are valid only if it is a square

Step-by-Step Solution

88 + 92 + 94 + 90 = 364, which is more than 360°, so the measurements cannot be correct.
Answer: B) They are invalid; the angles add to 364°
