Which angles are adjacent angles
Adjacent angles are two angles that have a common vertex and a common side between them.
Adjacent angles are angles that have a common vertex and a common side between them. Here are the types of adjacent angles:
1. Linear Pair: Two adjacent angles that form a straight line are called a linear pair. The sum of their measures is always 180 degrees.
2. Vertical Angles: When two lines intersect, the angles that are opposite each other are called vertical angles. Vertical angles are always congruent, which means they have the same measure.
3. Complementary Angles: Two angles are said to be complementary if the sum of their measures is 90 degrees. Complementary angles don't have to be adjacent, but when they are, they are called adjacent complementary angles.
4. Supplementary Angles: Two angles are said to be supplementary if the sum of their measures is 180 degrees. Similarly to complementary angles, when adjacent angles form a straight line and have a sum of 180 degrees, they are called adjacent supplementary angles.
So, adjacent angles can be linear pairs, vertical angles, complementary angles, or supplementary angles depending on their relationship.
