Adjacent Angles

Define adjacent angles.

Adjacent angles are angles that share a common vertex and a common side but do not overlap.

How do you identify adjacent angles?

Look for angles that are next to each other and share a common vertex and a common side.

Can adjacent angles be obtuse or reflex angles?

Yes, adjacent angles can be obtuse (greater than 90 degrees) or reflex (greater than 180 degrees) as long as they meet the criteria of sharing a common vertex and side.

What is the difference between adjacent angles and vertical angles?

Adjacent angles share a common vertex and a common side, while vertical angles are formed by two intersecting lines and are opposite each other. Vertical angles are always congruent, while adjacent angles may or may not be congruent.

What is the sum of adjacent angles in a straight line?

The sum of adjacent angles in a straight line, also known as a linear pair, is always 180 degrees.

What are some real-life examples of adjacent angles?

Examples of adjacent angles include the angles formed by the hands of a clock, the opening of doors, the intersection of roads, and the corners of geometric shapes like rectangles and triangles.

Adjacent angles are one of the many types of angles defined in geometry. They can be observed frequently in our day-to-day lives, from the opening of doors to the arrangement of book pages to the folding of paper. In this article, we explore the presence of adjacent angles in real-life scenarios.
