Question

clasificar cada figura como una recta, semirrecta o segmento de recta. luego,

figura	tipo	cómo se escribe

|(a) a b <-- |recta
semirrecta
segmento de recta|
|(b) e f <-- -->|recta
semirrecta
segmento de recta|
|(c) d c |recta
semirrecta
segmento de recta|

Explanation:

Step1: Identify line - types

A ray (semirrecta in Spanish) has one endpoint and extends infinitely in one direction. A line (recta) extends infinitely in both directions. A line - segment (segmento de recta) has two endpoints.

Step2: Analyze figure (a)

It has one endpoint (A) and extends infinitely in the direction away from B, so it is a ray. In notation, it is written as $\overrightarrow{AB}$.

Step3: Analyze figure (b)

It extends infinitely in both directions, so it is a line. In notation, it can be written as $\overleftrightarrow{EF}$.

Step4: Analyze figure (c)

It has two endpoints D and C, so it is a line - segment. In notation, it is written as $\overline{DC}$.

Answer:

(a) Tipo: semirrecta, Cómo se escribe: $\overrightarrow{AB}$
(b) Tipo: recta, Cómo se escribe: $\overleftrightarrow{EF}$
(c) Tipo: segmento de recta, Cómo se escribe: $\overline{DC}$
