Classify each pair of numbered angles.

Drag and drop the descriptions into the boxes to correctly classify each pair of numbered angles. Each description may be used more than once.

none of these
vertical
linear pair
adjacent

(1) Option B: The angles 1 and 2 are vertical angles

(2) Option D: The angles 3 and 4 are adjacent angles.

Explanation:

(1) When two lines are crossed, the angles lie opposite to each other and they share the same common point. These angles are called vertical angles.

From the figure, it is obvious, that the angles 1 and 2 share the same common point that is formed by the intersection of two lines.

Hence, the angles 1 and 2 are vertical angles.

Thus, option B is the correct answer.

(2) The angles does not overlap, share the same vertex and have the common side are called as adjacent angles.

From the figure, it is obvious that the angles 3 and 4 share the same vertex and have the common side and does not overlap each other.

Thus, the angles 3 and 4 are adjacent angles.

Hence, Option D is the correct answer.
