Question

1. choose true or false. the common endpoint of the rays of an angle is called the vertex. false true 2. choose true or false. a ray that bisects an angle into two congruent angles is a linear pair of angles. false true

Explanation:

Question 1

By the definition of an angle, an angle is formed by two rays with a common endpoint, and that common endpoint is called the vertex. So the statement is correct.

A ray that bisects an angle into two congruent angles is an angle bisector. A linear pair of angles are two adjacent angles whose non - common sides form a straight line. These are two different concepts, so the statement is false.

Answer:

True
