Answer:
1. DNK 2. RNX 3. DNX 4. KNA and DNE
Explanation:
1. If the angles are vertical, then they are reflected across their vertex
2. If two angles are complementary then they will add up to be 90, or inversely, if two angles add up to be 90, then they are complementary.
3. Supplementary angles add up to 180 such as two angles along a straight line.
4. If two of the angles have a common vertex and share a common side they are called adjacent angles
