Examples of Adjacent Angles

Some of the common examples of adjacent angles are discussed as follows:

Door Hinges

When a door is opened or closed, the angles formed between the door and the door frame are adjacent angles. These angles share the door hinge as the common vertex and the door frame as the common side.

Paper Folding

Folding a piece of paper to form intersecting creases creates adjacent angles where the creases meet. The creases serve as the common sides, and their intersection is the common vertex of the adjacent angles.

Street Intersections

At street intersections, the roads often meet at angles. The angles formed between two intersecting roads are adjacent angles, with the intersection point serving as the common vertex and the roads serving as the common sides.

Book Pages

When a book is open, the pages form adjacent angles where they meet at the spine. The spine of the book acts as the common side, and the corner where the pages meet serves as the common vertex.

Ladder Leaning Against a Wall

If a ladder is leaning against a wall, the angles formed between the ladder and the ground are adjacent angles. The ground and the wall serve as the common sides, and the point where the ladder touches the ground is the common vertex.

Hands of a Clock

The hands of a clock form adjacent angles as they move around the clock face. At any given time, the minute and hour hands form adjacent angles with the center of the clock serving as the common vertex.

Polygon Corners

In polygons such as triangles, quadrilaterals, and pentagons, the corners where the sides meet form adjacent angles. These angles share the common sides of the polygon and the vertex where the sides intersect.
