Angles That Share A Vertex
How to Name an Angle in Four Ways
- Math Lessons >
- Naming Angles
Information technology'south fourth dimension we closely examined an angle.
No matter how many angles are there in a diagram, each angle has its own unique name. We use the symbol '∠' followed by the name to represent an angle. The beneath links have more than on how you can label an bending and in how many different means you tin can accomplish this job.
1. Characterization an angle using the vertex and a point from each arm
2. Label an angle using merely the vertex
3. Characterization an angle using numbers
Label an bending using the vertex and a bespeak from each arm
∠ ABC or ∠ CBA
Note:
The vertex should go between the ii points.
Label an bending using only the vertex
∠ B
Note:
When two or more than angles share the same vertex, we don't use merely the vertex to name the angles.
Characterization an angle using numbers
∠ 1
Notation:
Sure lower-example letters of the English language alphabet similar a, b, and c, and Greek letters similar alpha (α), beta (β), gamma (γ), and theta (θ) are besides used to represent angles.
Solved Examples
one. Name this angle.
At that place are four ways we can name this bending: ∠FGH,∠HGF,∠G,∠1.
2. Locate ∠DBC in the figure.
∠DBC is highlighted in the image below.
Take up the challenge!
The below moving picture has 5 equally its vertex. The task is for you to identify and name all the angles that tin be formed from within the image.
∠PVQ or ∠QVP, ∠QVR or ∠RVQ, and ∠PVR or ∠RVP
