Adjacent Interior Angles

The angle adjacent to 145º will form a straight angle along with 145º adding to 180º.

Adjacent interior angles. In the below diagram you can see that 2 is an exterior angle. Here the word adjacent is used in its ordinary english meaning of next to each other. Any two interior angles that share a common side are called the adjacent interior angles of the polygon or just adjacent angles.

Have common vertex common point have common side also known as common arm must not overlap they should not have a common interior point. Adjacent angles are those. Any two interior angles that share a common side are called the adjacent interior angles of the polygon or just adjacent angles.

So 5 is adjacent interior angle to 6 in the below diagram you can see that 1 is an exterior angle. Adjacent interior angles are shown with diagram in following. Adjacent angles are two coplanar angles that have a common side between them but have no interior points in common.

Two angles are adjacent when they have a common side and a common vertex corner point and don t overlap. So 3 is adjacent interior angle to 2 in the below diagram you can see that 6 is an exterior angle. Let s point the conditions.

Now use rule that sum of s in δ 180º. 35 80 x 180 115 x 180 x 65. That angle is 35º.

Therefore the sum of the interior angles is always 180 2 exterior angles an exterior angle of the triangle is the angle between one side of a triangle and the extension of an adjacent side. Adjacent angles must have same vertex and common side other side of the angles are on the opposite sides of the common side. In the above triangle a b c are interior angles while d is an exterior angle.
