Adjacent Angles Definition. Adjacent angles are two angles that share a common side and a common vertex, and do not overlap. In the given diagram, the angles ∠ A B D and ∠ C B D are adjacent angles. They share the common arm or common side BD and a common vertex B.

Two angles are said to be adjacent angles when they have a common arm (side) and a common vertex and should not overlap. Adjacent angles are those angles that are always placed next to each other.
Since an angle is formed when two rays meet at a common endpoint, adjacent angles are simply two angles that are directly next to each other. Adjacent angles can be complementary angles or supplementary angles. For example, in this diagram, angle XW Y X WY is adjacent to angle Y W Z YW Z.
It is best to learn to understand whether the angles are adjacent or not on specific examples. EXAMPLE: In each case determine whether the angles 1 and 2 are adjacent or not. SOLUTION: a) Pair of angles ∠1 and ∠2 share the common vertex O and common arm $\vec {OB}$, so these angles are adjacent.
Adjacent angles can be defined as two angles with a common vertex and a common side. Adjacent angles can either be complementary or supplementary angles when they share a common vertex or side. Here, \(\angle{AOC}\) and \(\angle{BOC}\) are adjacent angles as they share a common vertex (O) and a common side (OC).
Home Contact About Subject Index. Adjacent Angles. Definition: Two angles that share a common side and a common vertex, but do not overlap. Try this Drag the orange dot. The line AC is the common leg of the two adjacent angles. In the figure above, the two angles ∠ BAC and ∠ CAD share a common side (the blue line segment AC).
