What does it look to have two parallel lines that are intersected by a third line perpendicular to the parallel lines?

It looks like a ladder with only one step, a railroad track with only one tie,
or the upper-case letter ' H '.

Two lines perpendicular to the same line are perpendicular to each other true or false?
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. !!!!!
Why can three coplanar lines have zero one two or three points of intersection?
If all three lines are parallel, there are zero points of intersection. If all three lines go through a point, there is one point of intersection. If two lines are parallel and the third one crosses them, there are two. If the three lines make a triangle, there are three points.
What is a median median line?
It is the line joining the midpoints of two sides of a polygon - usually a triangle. This line will be parallel to the third side. The three median-median lines will divide any triangle into 4 congruent triangles that are similar to the original.It is the line joining the midpoints of two sides of a polygon - usually a triangle.

Are three lines always coplanar?
No. Normally, two lines will uniquely identify a plane, unless they happen to be parallel. If you add a third line, it will usually not be in the same plane.* * * * *Not quite. Two lines that meet will uniquely identify a plane. But you can have lines that are neither coplanar nor parallel.For example, consider a cube and think of the line defined by the front bottom and one of the back verticals. Neither parallel, nor coplanar.
How do you divide a rectangle into 7 equal parts with 3 lines only?
To divide a rectangle into 7 parts using 3 lines: Use 2 lines to draw two diagonals. Use the third line to draw a parallel line to any of the sides but not passing through the centre
If two parallel planes are intersected by a third plane the lines of intersection are parallel.?
Yes, they are.
What is it called when two parallel lines are intersected by a third line?
The third line is known as a transversal.
If one of two parallel lines is perpendicular to another line is the other of the two lines parallel to the third line?
since one parallel lines is perpendicular to another line, the other parallel line is perpendicular to the line as well. so the two would not be parallel, only the original two.
When two lines are both intersected by a third line the non-adjacent angles which are in the interior of the two lines and on opposite sides of the intersecting line are called?
If the intersected lines are parallel then the angles are called equal alternate angles
What shape has 2 parallel lines and a third line that is perpendicular?
A capital "H."
What is a pair of angles formed by two lines intersected by a third line?
More info needed. Are the 2 lines parallel, perpendicular, or? are the angles that you are interested in on opposite sides of the intersecting line or the same side. The intersecting line is called a transversal. If the original lines are parallel, angles between the 2 lines on opposite sides of the transversal are called alternate interior angles, etc.
What quadrilateral has two right angles one set of parallel lines and two sets of perpendicular lines?
If by two sets of perpendicular lines you mean two pairs of perpendicular lines we can do it. One set of parallel lines is easy so draw that as the first and second lines A right angle from one of them will intersect the other at a right angle so that's the third line and the right angles sorted. The fourth side cannot be parallel to the third so draw it at an angle to the third. We now have two right angles, one set of parallel lines and two pairs of perpendicular lines, first and third, and second and third. What we call it depends on where we are. In the UK it is called a trapezium and in the USA a trapezoid. I'm afraid I don't know naming conventions in other countries.
What is a perpendicular with paralles lines?
If there are given two parallel line L1 and L2, and a third line L3 that is perpendicular to L1, then the line L3 must also be perpendicular to L2.
A pair of angles formed by two lines intersected by a third?
There are at least 28 different pairs of angles: 66 if the first two lines are not parallel. Your question needs to be more specific as to which angles you mean.
Which statement best shows the similarity in constructing a pair of parallel lines and a pair of perpendicular lines?
third choice, both do not require the use of a compass to draw arcs
Two lines perpendicular to the same line are perpendicular to each other true or false?

How are parallel lines perpendicular to the same line?
If you have two parallel lines, then they have the same slope. If you have another line, in the same plane as the first two lines, and it is not parallel to them, then the angle of intersection with the first line will be the same as the angle of intersection with the second line. If this angle is 90°, then the third line is perpendicular to the first line and also to the second line. For an example, think of a rectangle. Two opposite sides are parallel. Now pick one of the 3rd or 4th sides. Each of these sides is perpendicular to both the first side and the second side.
