Question

\\(\overleftrightarrow{vs}\\) bisects _______

select one:
a. \\(\angle tps\\)
b. \\(\angle rpt\\)
c. \\(\angle qpu\\)
d. \\(\angle qpr\\)

Explanation:

Identify the geometric elements

We are given a geometric diagram with intersecting lines and rays meeting at point \(P\).

• Line \(QT\) and line \(VS\) intersect at point \(P\).
• Ray \(PU\) and ray \(PR\) form a vertical line, with \(PR \perp QT\) as indicated by the right-angle symbol at \(\angle QPR\).
• We need to determine which angle the line or segment \(\overline{VS}\) (or ray \(PV\) / \(PS\)) bisects.

Analyze the angle markings

Using the Angle Bisector knowledge point:

• There are congruency tick marks on several angles.
• Specifically, \(\angle QPV\) has a single arc mark with a tick mark.
• \(\angle SPR\) has a single arc mark with a tick mark.
• Therefore, \(\angle QPV \cong \angle SPR\).

Apply vertical angle relationships

Using the Vertical Angles knowledge point:

• Since line \(QT\) and line \(VS\) intersect at \(P\), \(\angle QPV\) and \(\angle TPS\) are vertical angles.
• Therefore, \(\angle QPV \cong \angle TPS\).

Relate the congruent angles

Combining our previous observations:

• Since \(\angle QPV \cong \angle SPR\) and \(\angle QPV \cong \angle TPS\), by the transitive property of congruence, we have:

$$\angle TPS \cong \angle SPR$$

• This means ray \(PS\) divides \(\angle TPR\) (or \(\angle RPT\)) into two congruent adjacent angles, \(\angle TPS\) and \(\angle SPR\).

Determine the bisected angle

• Since ray \(PS\) lies on the line \(\overline{VS}\) and divides \(\angle RPT\) into two congruent angles \(\angle TPS\) and \(\angle SPR\), the line \(\overline{VS}\) bisects \(\angle RPT\).

Answer:

• a. \(\angle TPS\)
• b. \(\angle RPT\) (Correct answer)
• c. \(\angle QPU\)
• d. \(\angle QPR\)
