Question

Which pairs of angles in the figure below are vertical angles?

Answer 1

Answer: C

Explanation: In the diagram shown, <ISN and <TSW

are called vertical angles.

Vertical angles, such as angles <ISN and <TSW can be

defined as angles the share a common vertex, in this case x,

and whose sides form opposite rays.

Answer 2

Answer:

C. Angles ISN and TSW

Explanation:

The definition of vertical angles is "each of the pairs of opposite angles made by two intersecting lines."

In the image lines WN and TI intersect at vertex S to create opposite (vertical) angles ISN and TSW.
