What else can I help you with?
Why are corresponding angles equal?
If the two lines being crossed are parallel lines then the corresponding angles are equal.
Angles that lie outside of two parallel lines that are crossed by a transversal line?
perpendicular
Is hyperbolic parallel postulate a postulate of Euclid?
No, the hyperbolic parallel postulate is not one of Euclid's original five postulates. Euclid's fifth postulate, known as the parallel postulate, states that given a line and a point not on that line, there is exactly one line parallel to the original line that passes through the point. Hyperbolic geometry arises from modifying this postulate, allowing for multiple parallel lines through the given point, leading to a different set of geometric principles.
How do you label parallel lines?
To indicate that a pair of lines are parallel you mark them both with an arrow. If there is another pair of parallel lines on the same shape you mark those with a double arrow.
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 parallel lines are crossed by another line. what is it?
two parallel lines are crossed by another line ,that's the perpendicular.
What are lines that never crossed called?
Parallel lines are lines that never cross.
Why do corresponding angles always have to be the same?
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.
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.
Why are corresponding angles equal?
If the two lines being crossed are parallel lines then the corresponding angles are equal.
Angles that lie outside of two parallel lines that are crossed by a transversal line?
perpendicular
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?
Can lines on different planes be parallel?
Yes, they can. Since three points define a plane, take any two points on one line and a point on the other line, and form the plane with those three points. Once you have that, then use Euclid's test to see if they are parallel. Alternately, if the planes themselves are parallel, then the lines are as well, since they definitely will never intersect.
Who studied points lines angles and planes relate to one another?
Euclid.
What is equidistant lines?
Parallel lines are equidistant from one another

If there is a line and a point not on the line then there is exactly lines trough the point parallel to the given line?
This is Euclid's fifth postulate, also known as the Parallel Postulate. It is quite possible to construct consistent systems of geometry where this postulate is negated - either many parallel lines or none.
