How to find the vertex angle? - GeeksforGeeks

WebAn angle is a figure formed by two rays or line segments. We can observe angles on objects all around us. The two rays that form an angle have a common intersection point known as the vertex of the angle. The two rays that make an angle are known as the arms of the angle.. We use the symbol ∠ to represent an angle. Angles are measured using … WebAnd then we can get another angle. So let's try to measure this one right over here. So once again, place the center of the protractor at the center, at the vertex, of our angle. We can place the 0 degree, the base of the protractor, at this side of the angle. So let's just rotate it a little bit, maybe one more time.
