That's true.
a double line graph is a graph that is same as a line graph but there are two lines
No! Bar and line graphs are different bar graphs show bars and line graph shows lines.
You can compare two different data sets on the same chart.
The advantage is that you can compare multiple data sets in the same chart
a double line graph is a graph that is same as a line graph but there are two lines
They are two lines that are on top of each other, so they are the same line.
No
They are parallel to each other.
Then they are at right angles to each other
Collinear lines are on the same line.
TRUE:: The first two lines lie in the same plain, but are perpendicular to each other. The third line passes through the plane of the first two lines so it is also perpendicular. Think 3-dimension. !!!!!
If two lines are parallel to the same line, then they are parallel to each other.
If two lines are parallel to the same line, then they are parallel to each other.
the parallel lines never intersect each other but they both intersect the line they are perpendicular to
Yes they are. It's a postulate: In a plane two lines perpendicular to the same line are parallel.
No. Two lines perpendicular to the same line are parallel to each other. I am doing this for my geometry homework right now trying to recall the name of the postulate/theorem stating it.
So long as all three lines are in the same plane, yes.
