# Adjacent Angles and Linear Pairs

Adjoining angles and linear pairsSome special relationships exist between the "pairs" of angles. ( They share a vertex and a side, but do not overlap.) A linear pair is two adjacent angles whose unusual sides form opposite rays. Linear angle pairs are two adjacent angles whose unusual sides form a straight line. Adjoining angles and vertical angles always have a common vertex, so they are literally connected at the hip.

There are two angles in a linear pair next to each other.

Is it possible for two angles to make a linear couple and not lie next to each other?

Do you ask for additional angles that would amount to 180-degree? They do not have to be adjacent to be complementary, but if they are adjacent to each other by crossing line, they are referred to as a line couple. And there is exactly this conceptual difference: if you divide these angles, they are still complementary, but no longer a linear couple.

Line pairs are two adjacent angles that have a total of 180 degree, forming a line. They can have two angles which are complementary, but not adjacent, so that they are not a linear couple, but only complementary. The angles DAB and BCD are right angles.

The angles DAB and DCB are complementary. However, the angles DAB and DCB do not divide a joint beam, they are not adjacent. The angles DAB and DCB are not a linear couple.

## Acquaintance with angle pairs

Adjoining angles and perpendicular angles always have a shared apex, so they are connected to each other verbatim at the waist. Complimentary and supplemental angles can divide a node, but do not have to. These are the definition for the different pairs of angles: Adjoining angles: Adjoining angles are adjacent angles that have the same apex and divide one side; moreover, no angles can lie in the other.

Neither of the untitled angles to the right is adjacent because they either do not divide a knot or no side. When you have adjacent angles, you cannot name any of the angles with a unique character. Instead, you must use a number or three characters to relate to the relevant corner.

Complimentary angles: The two angles that are added to 90° (or a right angle) complement each other. You can be adjacent angles, but you don't have to be. Additional angles: There are two angles that sum up to 180 (or a flat angle). It can be adjacent angles or not. These pairs of angles are known as linear pairs.

The angles A and z are complementary because they sum to 180°. Upright angles: Angles on the opposite sides of the triangle are referred to as perpendicular angles when crossing line forms line. There are two perpendicular angles that are always the same value. Incidentally, as you can see in the illustration, the verticals in perpendicular angles have nothing to do with the up and down significance of the verticals.
