In Figure 2.6, name Five points, A line, Four rays, Five line segments

In Figure 2.6, name Five points, A line, Four rays, Five line segments Class 6

Question 1.

In Figure 2.6, name: Class 6

1. Five points

2. A line

3. Four rays

4. Five line segments

Answer:

1. Five points are B, O, C, D, and E.

2. [latex]\overleftrightarrow{\mathrm{BD}}[/latex] or [latex]\overleftrightarrow{\mathrm{DE}}[/latex] or [latex]\overleftrightarrow{\mathrm{EO}}[/latex] or [latex]\overleftrightarrow{\mathrm{DO}}[/latex] or [latex]\overleftrightarrow{\mathrm{BO}}[/latex] or [latex]\overleftrightarrow{\mathrm{BE}}[/latex] (same line).

3. [latex]\overrightarrow{\mathrm{OB}}, \overrightarrow{\mathrm{OC}}, \overrightarrow{\mathrm{~EB}}, \overrightarrow{\mathrm{DB}}[/latex]

4. [latex]\overline{\mathrm{DE}}, \overline{\mathrm{DO}}, \overline{\mathrm{EO}}, \overline{\mathrm{OB}} \text { and } \overline{\mathrm{OC}}[/latex]

Question 2.

Here is a ray [latex]\overrightarrow{\mathrm{OA}}[/latex] (Fig. 2.7). It starts at O and passes through the point A. It also passes through point B. Class 6

1. Can you also name it as [latex]\overrightarrow{\mathrm{OB}}[/latex]? Why?

2. Can we write [latex]\overrightarrow{\mathrm{OA}}[/latex] as [latex]\overrightarrow{\mathrm{AO}}[/latex]? Why or why not?

Answer:

1. Yes. Because it also starts at O and extends indefinitely in the same direction as A.

2. No. Because starting point of [latex]\overrightarrow{\mathrm{OA}}[/latex] is O and that of [latex]\overrightarrow{\mathrm{AO}}[/latex] is A.
