Question

Fill in the blank:-
The common endpoint of two rays or line segments forming an angle is called the ______ of the angle.

Answer 1

Hint:Before solving this question, let us know about Ray, Line Segment, and Vertex.Then see which of the following matches that is asked in the question and get the required result.
Complete step by step answer:
RAY: A ray can be defined as a part of a line that has a fixed starting point but no end point. It can extend infinitely in one direction.

LINE SEGMENT: A line segment is a part of a line that has fixed end points and does not extend from both the sides.

VERTEX: A vertex is a point where two or more curves, lines, or edges meet.

As mentioned in the hint provided above, the point where two or more curves, lines or edges meet is called a vertex.
The point where two rays or line segments of an angle meet is also known as the vertex of the angle.
Therefore, the answer to this question is vertex.
The word that will fill the blank is ‘vertex’

Note:Let us now know about lines and arms of an angle.
LINE: A line is defined as a line of points that extends infinitely in both the directions. It has just one dimension, which is length.
ARMS OF AN ANGLE: Any of the two lines that form the angle are called the arms of the angle.
