How do you graph parallel and perpendicular lines?
If you want to graph parallel lines, they need to have the same slope (Ex. 2x+2 and 2x+3)- parallel lines cannot have the same y-intercept because the two line would be the same. Perpendicular lines slopes need have to be opposite reciprocals (Ex. -2x+4 and +1/2x+3)- perpendicular lines can have the same y-intercepts, it doesn't make a difference.
Why do parallel lines always make vertical angles?
Wrong statement. Parallel lines don't always make vertical angles without the transversal, the line that passes through these lines. Without the transversal, we can't make the conclusion that parallel lines form vertical angles.
If two lines are perpendicular they are also parallel?
PARALLEL AND PERPENDICULAR LINESParallel lines can run side by side on forever but perpendicular lines make a 90 degree angle.
Can I make a quadrilateral with only one pair of parallel sides?
no? because in order to be a quadrilateral you need 4 sides. a pair of parallel lines in just 2 lines. parallel lines also never touch.
How do you make a rectangle that is not a parallelogram?
You can't... A rectangle is defined by 2 sets of parallel lines, ans a parallelogram has 1+ sets of parallel lines
What are the two parallel lines that cant intersect?
The question does not make sense. Parallel lines, by definition, do not intersect.
How do you graph parallel and perpendicular lines?
If you want to graph parallel lines, they need to have the same slope (Ex. 2x+2 and 2x+3)- parallel lines cannot have the same y-intercept because the two line would be the same. Perpendicular lines slopes need have to be opposite reciprocals (Ex. -2x+4 and +1/2x+3)- perpendicular lines can have the same y-intercepts, it doesn't make a difference.
Why does it make sense that slopes of perpendicular lines have opposite signs?
Because if one of the pair of lines is going from bottom left to top right, the other is going from bottom right to top left.
How many parallel lines does a pentagon have?
A regular pentagon has no parallel lines, but you can create an irregular pentagon with one pair of parallel lines if you make a traditional 'house' shape with parallel 'walls'.

Are the metal rails that make up train an example of parallel line intersecting lines or perpendicular lines?
Railway lines are parallel
Why do parallel lines always make vertical angles?
Wrong statement. Parallel lines don't always make vertical angles without the transversal, the line that passes through these lines. Without the transversal, we can't make the conclusion that parallel lines form vertical angles.
What pattern do topo lines make around hills and mountains?
Topo lines form concentric circles around hills and mountains. The lines are closer together on steeper slopes, and farther apart on gentler slopes. The lines never cross, and uphill is always perpendicular to the lines.
Are the metal rails that make up train tracks an example of parallel lines intersecting lines or perpendicular lines?
On successful railways it has been found that parallel works the best.
Is a rectangle and a parallelogram the same?
A rectangle is a type of parallelogram. A parallelogram by nature is a geometric shape where two sides are parallel to each other. Parallel lines run in the same direction with the same distance between them for their entire length. If the lines are extended to infinity, the lines will never intersect. A rectangle is composed of two sets of parallel lines. Two parallel lines make up the top and bottom and two parallel lines make up each side.
If two lines are perpendicular they are also parallel?
PARALLEL AND PERPENDICULAR LINESParallel lines can run side by side on forever but perpendicular lines make a 90 degree angle.
