Answer :
Answer:
opposite angles
Step-by-step explanation:
- If a quadrilateral is inscribed in a circle, then its opposite angles are supplementary.
- This is known as the "Opposite Angles of a Cyclic Quadrilateral Theorem" or Theorem 7.5D.
- This means that the sum of each pair of opposite angles in the quadrilateral equals 180 degrees.
- This property holds for any quadrilateral inscribed in a circle, providing a useful geometric relationship in circle geometry problems.
