Respuesta :
The statement that is always true is:
- Parallel lines are always coplanar.
- Perpendicular lines are always coplanar.
- Distance around an unmarked circle can never be measured.
This is further explained below.
Determine if each statement is always, sometimes, or never true.?
Generally, This is shown in Figure 1, as can be seen.
Because it is obvious that both the red line and the blue line are situated on the same plane, we may conclude that lines that are parallel are always co-planar.
This is shown in the second figure. As can be seen, the lines in the red and blue form a right angle with one another.
Take note of the fact that the red line can be found on both aircraft M and plane N,
however, the blue line can only be seen on plane N. As a result, the two lines are parallel to one another on plane N.
In conclusion, lines that are perpendicular to one another are always on the same plane.
In conclusion, in order to estimate the distance, we need a circle that has been marked.
Therefore, the radius is defined as the distance that extends outward from the center of the circle to one of its points. In addition, the diameter of the circle is determined by the distance that exists between two places on the circle when a line is drawn through the center of the circle.
