Question

directions - name each geometric part with its correct name.
(1)
(2)
(3)
(4)
line dc
line
segment
cd
ray cd
plane dc

Explanation:

Step1: Identify geometric - part 1

A ray has one endpoint and extends infinitely in one direction. The first figure with an arrow - head on one side starting from point C is a ray. So it is Ray CD.

Step2: Identify geometric - part 2

A line segment has two endpoints. The second figure with two endpoints is a line segment. So it is Line segment CD.

Step3: Identify geometric - part 3

A line extends infinitely in both directions. But here we assume it's a line segment as it has two endpoints W and X. So it is Line segment WX (not in the given options but conceptually a line segment).

Step4: Identify geometric - part 4

A plane is a flat, two - dimensional surface that extends infinitely far. The fourth figure is a plane. But the naming convention for a plane usually uses three non - collinear points or a single capital letter. Since the given options have "Plane DC" which is an incorrect naming (usually we need three non - collinear points), but among the options, for a plane, we would choose Plane DC as the closest match.

Answer:

(1) Ray CD
(2) Line segment CD
(3) Line segment (not in options but conceptually)
(4) Plane DC
