1. write the correct symbol/notations for each of the following

• segment df
• line ts
• angle abc
• ray gh
• segment vz is perpendicular to segment vw
• the measure of angle q is 46 degrees
• line op is parallel to line mn

Explanation:

Step1: Segment DF

A segment is denoted by its two endpoints with a bar over them. So segment DF is $\overline{DF}$.

Step2: Line TS

A line is denoted by its two points with a double - headed arrow over them. So line TS is $\overleftrightarrow{TS}$.

Step3: Angle ABC

An angle is denoted by the symbol $\angle$ followed by the three points (vertex in the middle). So angle ABC is $\angle ABC$.

Step4: Ray GH

A ray is denoted by its starting point and another point on the ray with an arrow starting at the first point. So ray GH is $\overrightarrow{GH}$.

Step5: Segment VZ is perpendicular to segment VW

Perpendicularity is denoted by the symbol $\perp$. So we write $\overline{VZ}\perp\overline{VW}$.

Step6: The measure of angle Q is 46 degrees

The measure of an angle is denoted by $m\angle$ followed by the angle name, and then we set it equal to the measure. So $m\angle Q = 46^{\circ}$.

Step7: Line OP is parallel to line MN

Parallelism is denoted by the symbol $\parallel$. So we write $\overleftrightarrow{OP}\parallel\overleftrightarrow{MN}$.

Answer:

• Segment DF: $\boldsymbol{\overline{DF}}$
• Line TS: $\boldsymbol{\overleftrightarrow{TS}}$
• Angle ABC: $\boldsymbol{\angle ABC}$
• Ray GH: $\boldsymbol{\overrightarrow{GH}}$
• Segment VZ is perpendicular to segment VW: $\boldsymbol{\overline{VZ}\perp\overline{VW}}$
• The measure of angle Q is 46 degrees: $\boldsymbol{m\angle Q = 46^{\circ}}$
• Line OP is parallel to line MN: $\boldsymbol{\overleftrightarrow{OP}\parallel\overleftrightarrow{MN}}$
