In this post, we’re going to find out the meaning of vertical angles and the adjacent angles in addition to how to determine these angles. Before we get started, we should first get familiar with the following ideas regarding lines.
Vertical and adjacent angle are two distinct kinds of angles. These angles form the main concept of geometry that was which we learn in Classes 4, 5 and 6. They are the fundamental concept that we study throughout the academic curriculum. There are a variety of kinds of angles we study in school.
The measurement of the ray’s rotation when it rotates around its endpoint is known as the angle created by the ray that is between its starting and its final position. An angle is created by two rays that are connected from end to end.
Sometimes, in geometries, the use of an angle pair is utilized. There is a variety of combinations of angles such as supplementary angles, adjacent angles, complementary angles, linear pairs of angles and so on. In this article, we’re going to go over how to define adjacent angles as well as vertical angles in depth.

Vertical Angle
When two lines cross and intersect, they form naturally two sets of vertical angles. Vertical angles have the same vertex or corner they are opposite to each other. The two angles are congruent which means they share the same measurement of angle. We can measure such types of angles by using a vertical angle solver, it calculates the vertical angles in the blink of an eye.
What are Vertical Angles?
It is a pair formed by the intersection of two lines. Vertical angles are often called vertically opposite angles due to the angles being opposite from one another.
In real-world settings, vertical angles are employed including railroad crossing signs with letters ” X‘”, open scissors, and pliers. The Egyptians utilized two intersecting lines, and then take a look at the angles of the vertical to ensure that they are equal.
Horizontal angles are always identical to each other. In general, it is possible to claim that two pairs of angles vertical form when two lines cross. Check out the diagram below.
In the above diagram:
- A and C are vertically opposite angles. Both angles are identical so we write them as A = A.
- Similarly, B and D form another pair of angles that are vertical and they are also equal i.e. B = B
- We could also claim that the two angles have a common vertex (the common terminus of two lines or Rays).
Vertical Angles Definition
Vertical angles can be described as not adjacent angles formed by the junction of straight lines. In simple terms, they are located between at their corners within the “X” formed by two straight lines. They are often referred to as opposing angles vertically because they are opposite to each other.
The theorem of Vertical Angle
The perpendicular angle theorem, also known as the perpendicular angle theorem explains that the two angles created when two lines meet are always in a congruous manner. Let’s learn more about the theory of the vertical angle and the proof of it in depth.
The statement: Vertical angle (the opposite angles formed when two lines meet one another) is congruent.
Measuring the Required angle
You can apply the knowledge you have gained about angles in the vertical direction to determine missing angles.
Consider finding the DCE measure. DCE ACB and DCE ACB can be described as vertical angles. They are opposite to each other with two lines crossing each other. Because DCE, as well as ACB, can be described as vertical angles, the two are incongruity. Therefore, the measurement of DCE is 60 degrees.
Moreover, you can also try Calculatores which provides a number of tools to solve the different sorts of problems in maths, physics, chemistry and many more.
Adjacent Angles
Adjacent angles are angles with a shared arm (side) and the same vertex. However, they don’t overlap. An angle is created when two rays intersect at an endpoint that is common to both. adjacent angles are those that are always in close proximity to each other. Learn the basics of adjacent angles on this article.
What are Adjacent Angles?
Two angles are considered to be adjacent angles when they share a common vertex on the same side and don’t overlap. Check out the figure below to see what the close angles appear to be. Angles 1 and 2 looks both adjacents because they share a common side BD, as well as an identical vertex B.
Adjacent Angles Definition
Adjacent angles are angles that are set next to one another in a manner that they have a common vertex as well as an identical side, but don’t overlap.
Adjacent Angles Examples
We can find many real-life examples of angles with adjacent angles.
- The most popular real-life illustration of angles that are adjacent can be observed on two slices of pizza placed on top of each other.
- Another example of this can be found in the clock, which displays minutes, hours and second hand which are adjacent angles when three of them are separate from each other.
- Three adjacent angles within the steering wheel in the car.
Property of Adjacent Angles
These characteristics of the adjacent angles given below will help us recognize them quickly.
- The angles that are adjacent always have an arm.
- They share a vertex.
- They do not cross.
- They have non-common arms that are on the opposite side of their common arm.
- Two angles adjacent to each other may be supplementary or complementary depending on the dimensions of the two angles.

FAQ’s
What are adjacent angles?
Adjacent angles can be described as angles that share an identical vertex and common side. Two adjacent angles may be either supplementary or complementary depending on their sum.
What is the definitions of Vertical Angles?
These are angles which are opposite to one other , when two lines intersect (i.e. intersect). This is also referred to in the context of vertically opposing angles. It is important to note that two angles on the vertical will always be equal.
Are Vertical Angles Adjacent?
The vertical angle will never be connected. Aspects that are adjacent are those adjacent to one another. Likewise, vertical angles are in opposition to one another.
