The angles described in the question form a 270° angle between each other, so they're neither complementary nor supplementary as complementary angles add to 90° and supplementary angles add to 180°.
The subject of this question is determining whether two given angles are complementary, supplementary, or neither. In geometry, complementary angles are two angles whose sums add up to 90 degrees. Supplementary angles, on the other hand, are two angles whose sum adds up to 180 degrees. From the given information, angle c and angle d form a 270° angle between each other, which means they are neither complementary nor supplementary. Complementary and supplementary angles are basic concepts in geometry that are used to study the properties of various shapes and patterns.
Now let's understand it with an example: for example angle a is 60° and angle b is 40°. So, if you add up 60° (from angle a) and 40° (from angle b), you get 100°. Since they do not add up to 90° or 180°, they are neither complementary nor supplementary.
