Solved Example on Vertex of an Angle
Ques: Which of the following figures has D as its vertex?
Choices:
A. Figure 4
B. Figure 3
C. Figure 2
D. Figure 1
Correct Answer: C
Solution:
Step 1: The point from which the two rays originate is the vertex of an angle.
Step 2: Here, the rays DE and DF originate from the point D.
Step 3: So, D is the vertex.
Step 4: Therefore, Figure 2 has an angle D as its vertex.
Quick Summary
- The vertex is the corner point of an angle.
- Angles are measured from the vertex.
