Answer 1

Answer:

C. <ISN and <TSW

D. <TSN and <ISW

Explanation:

When two straight lines intersect each other, the two pairs of the opposite angles formed are called vertical angles.

In the figure given, we have two straight lines, NW and IT, which crosses each other. They form two pairs of opposite angles. They are:

<ISN and <TSW;

<TSN and <ISW.

These pairs of angles formed are vertical angles.
