Ques: How many angles are formed by three rays with a common vertex?
Choices:
A. 3
B. 2
C. 1
D. 4
Correct Answer: A
Solution:
Step 1: The figure shown has three rays PQ, PR, and PS with a common vertex P.
Step 2: The angles formed by these 3 rays are QPR, RPS, and QPS.
Step 3: So, three rays can form 3 angles.
Quick Summary
- An angle is formed by two rays.
- The common endpoint of the rays is called the vertex.
