Question

clasificar cada figura como una recta, semirrecta o segmento de recta. luego, mostrar cómo se escribe.
(a)
figura: image of a line - like figure with points t and u and an arrow pointing left
tipo:
○ recta
○ semirrecta
○ segmento de recta
(b)
figura: image of a line - like figure with points p and q and arrows pointing both ways
tipo:
○ recta
○ semirrecta
○ segmento de recta
(c)
figura: image of a line - like figure with points s and r
tipo:
○ recta
○ semirrecta
○ segmento de recta

Explanation:

Step1: Recall definitions

A ray (semi - recta) 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 \(T\) and extends infinitely towards \(U\), so it is a ray. It is written as \(\overrightarrow{TU}\).

Step3: Analyze figure (b)

It extends infinitely in both directions, so it is a line. It is written as \(\overleftrightarrow{PQ}\).

Step4: Analyze figure (c)

It has two endpoints \(S\) and \(R\), so it is a line - segment. It is written as \(\overline{SR}\).

Answer:

(a) Tipo: semirrecta, Cómo se escribe: \(\overrightarrow{TU}\)
(b) Tipo: recta, Cómo se escribe: \(\overleftrightarrow{PQ}\)
(c) Tipo: segmento de recta, Cómo se escribe: \(\overline{SR}\)
