Question 27

Question. 27

The number of common points in the two angles marked in Fig. 2.18 is ____.

Answer:

2

Detailed Answer with Explanation:

Beginner-friendly steps

“Common points” means points that belong to both angles at the same time.

  1. Look at the vertex.
    Both angles are drawn from the same corner (the same vertex).
    This gives one common point: the vertex.
  2. Check the arms.
    The two angles share one arm (one boundary ray).
    On this shared arm, the marked angles meet at one more point.
  3. No other overlap.
    Apart from the vertex and that one point on the shared arm, there are no other common points.

So, the total number of common points is:

\(1\) (vertex) \(+\) \(1\) (on the shared arm)

= \(2\)
