Question 28

Question. 28

The number of common points in the two angles marked in Fig. 2.19 is ____.

Answer:

1

Detailed Answer with Explanation:

Think of “common points” as points that lie in both angles at the same time.

  1. Look at the figure. The two angles meet at the same corner.
  2. That corner is the vertex \(A\).
  3. The sides (rays) of the two angles go in different directions.
  4. These sides do not overlap each other.
  5. So, the only point that belongs to both angles is the vertex.

Write it step by step:

\(\text{Common points} = \text{points in both angles}\)

\(\text{Vertex of both angles} = A\)

\(\text{Arms do not overlap}\Rightarrow \text{no other shared point}\)

\(\therefore \text{Number of common points} = 1\)
