Step: 1

The number of angles in a closed plane figure made of line segments is equal to the number of sides of the figure.

Step: 2

The statement is true.

Correct Answer is : True

Step: 1

A ray is part of a line, which begins at a fixed end point.

Step: 2

So, a ray has one fixed end and the other end can be extended to any length.

Step: 3

Among the figures, Figure 1 has only one end point. So, it is a ray.

Correct Answer is : Figure 1

Step: 1

A ray is defined as a line starting at some point of the plane and proceeding outwards.

Step: 2

In the figure, QA is a line starting at point Q and proceeding outwards.

Step: 3

So, QA is a ray in the figure.

Correct Answer is : QA →

Step: 1

A line is a straight path that is endless in both directions.

Step: 2

In the figure, AB is a line, PQ, QR, and PR are the line segments, and PB, QB, and RB are the rays on the line AB.

Step: 3

So, AB ↔ is a line in the figure shown.

Correct Answer is : AB ↔
