# 10 Examples of Vertical Angles

October 14, 2023 written by Rida Mirza

In mathematics, vertical angles are a important concept. Vertical angles are formed when two lines intersect, and their opposing angles are congruent.

In this article, we will discuss ten examples of vertical angles in mathematics.

## Examples of Vertical Angles

These are 10 examples of vertical angles.

### 1: Open Scissors

When you open a pair of scissors, the two blades form an “X” shape. The angles formed at the intersection of the blades are vertical angles.

### 2: Book Pages

When you open a book, the pages often form vertical angles at the center crease.

The angle formed by each page with the center crease is a pair of vertical angles.

### 3: Carpenter’s Square

Carpenter’s squares, commonly used in woodworking and construction, have two arms that meet at a right angle.

The angles formed when the arms intersect are vertical angles.

### 4: Street Signs

Poles that support street signs often intersect with the horizontal and vertical bars, forming vertical angles.

### 5: Picture Frames

Picture frames with corners create vertical angles at the corners.

### 6: Traffic Lights

Bars holding traffic lights at intersections meet at specific angles. These angles are vertical angles.

### 7: Fences and Gates

Fences and gates often have vertical posts intersected by horizontal beams or bars. The angles at the intersection points are vertical angles.

### 8: Computer Screens

In dual-monitor setups, the screens are often aligned at an angle to meet the viewer’s eye level.

The angle at which the screens intersect is a pair of vertical angles.
