Webb1 juli 2024 · A pair of vertically opposite angles are always equal to each other. Also, a vertical angle and its adjacent angle are supplementary angles, i.e., they add up to 180 degrees. For example, if two lines intersect and make an angle, say X=45°, then its opposite angle is also equal to 45°. WebbStatements (I) and (II) are as given below: I: If two lines intersect, then the vertically opposite angles are equal. II: If a transversal intersects two other lines, then the sum of two interior angles on the same side of the transversal is 180°. Then, answer choices. a) both (I) and (II) are true. (b) (I) is true and (II) is false.
