Supplementary Adjacent Angles
Supplementary adjacent angles are pairs of adjacent angles whose measures add up to 180°. In other words, when two angles are supplementary, they form a straight line. However, in case of quadrilaterals such as parallelogramThis property is commonly observed in various geometric figures, including parallelograms, straight lines, and sometimes in triangles.
If you have a straight line, the angles on either side of the line are supplementary adjacent angles. For example, if angle A and angle B are adjacent angles on a straight line, then A + B = 180°.
In a parallelogram, opposite angles are congruent (have the same measure), and adjacent angles are supplementary. If angle A and angle B are adjacent angles in a parallelogram, then A + B = 180°.
Linear Pair Adjacent Angles
When adjacent angles form a straight line together, they are known as a linear pair. A linear pair of angles always adds up to 180°.
What is Adjacent Angle in Geometry?
Adjacent Angles are the angles that have a common vertex, a common arm, and the rest two arms lie on either side of the common arm. Angles are particularly important in geometry as they help define and understand different geometric figures and their characteristics. Geometry is a branch of mathematics that focuses on shapes, sizes, and angles. A key concept within geometry is adjacent angles. Understanding adjacent angles helps us grasp the geometry of lines, polygons, and other shapes.
In this particular article, we are going to learn about adjacent angles, their definitions, their properties, and some examples and we will also practice some questions on it.
