Question

geometry 1-1: measuring segments and angles
a segment is the part of a line that consists of two points, called endpoints and all points between them.
a ray is the part of a line that consists of one endpoint and all the points of the line on one side of the endpoint.
opposite rays are rays with the same endpoint that lie on the same line.
an angle is formed by two rays with the same endpoint. each ray is a side of the angle and the common endpoint is the vertex of the angle.

1. select all that apply:

the angle above can be denoted...
∠3
∠kjg
∠j
∠gjk

Explanation:

An angle can be named by a number if it is labeled with a number inside the angle, by three - letter notation where the middle letter is the vertex of the angle. In the given angle, the vertex is \(J\). \(\angle KJG\) and \(\angle GJK\) are correct three - letter notations for the angle. There is no indication that the angle is labeled as \(\angle3\), and \(\angle J\) is ambiguous as there could be multiple angles with vertex \(J\) in a more complex figure.

Answer:

B. \(\angle KJG\), D. \(\angle GJK\)
