Why do corresponding angles always have the same measurement?
They don't always. When two lines are crossed by another line (called the transversal) the angles in matching corners are called corresponding angles. If the two lines being crossed are parallel lines, then (and only then) the corresponding angles are equal.
I need a real life example of Parallel lines with a perpendicular transversal?
Railway lines with sleepers? Lines of latitude crossed by a line of longitude?
What does corresponding lines mean?
When two lines are crossed by another line (called the Transversal)
Why did you say that a certain line is parallel to other?
Lines that are equal distance from one another and never intersect are said to be parallel lines.
What line intersect through parallel lines?
No line can intersect parallel lines. Parallel lines by definition never intersect.
Angles that lie outside of two parallel lines that are crossed by a transversal line?
perpendicular
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.

What is another name for the line of laditude?
A Parallel - because they are imaginary lines that run around the earth parallel to the equator
What is the slope of a parallel line?
Parallel lines have the same slope. So if you have a line with slope = 2, for example, and another line is parallel to the first line, it will also have slope = 2.
How do you find the slope of a line parallel to another line?
The slope of both lines will be the same.

What line intersect through parallel lines?
No line can intersect parallel lines. Parallel lines by definition never intersect.
A line parallel to another line with an undefined slope must also have an undefined slope?
Sounds reasonable. If the lines are parallel, then their slopes are equal.
