With reference to the given diagram, name a pair of interior angles on the same side of the transversal.

Given, the figure, The same side interior angles are the pair of non-adjacent interior angles that lie on the same side of the transversal, have no common vertices or have different vertices, lie between two lines. Thus, in the figure, the pairs of interior angles on the same side of the transversal are: ∠ c , ∠ g .

With reference to the given diagram, name a pair of vertically opposite angles.

Given, the figure, We know that, When two lines intersect, the angles formed between the lines are called vertically opposite angles and the vertically opposite angles are equal. So, a pair of vertically opposite angles in the figure are ∠ b , ∠ d .

With reference to the given diagram, name a linear pair.

Given, the figure, From the figure, If the angles so formed are adjacent to each other after the intersection of the two lines, the angles are said to be linear. If two angles form a linear pair, the angles are supplementary, whose measures add up to 180 ° . Hence, a linear pair of angles always add up to 180 ° . Therefore, a pair of linear angles of the figure are ∠ g , ∠ f .

With reference to the given diagram, name a pair of adjacent angles.

Given, the figure, From the figure, We know that, Adjacent angles are angles with the same vertex that lie on opposite sides of the parallel line, but on the same side of the transversal. Therefore, a pair of adjacent angles of the given figure are ∠ h , ∠ e .
