Geometry begins with assumptions about certain things that are difficult, if not impossible to prove, and flows on things that can be proven. The assumptions that geometries logic is based on is called postulates. Sometimes. A transversal is a line the crosses at least two other lines.

What are transversal lines?
Transversal lines are made when one line crosses two parallel lines.
What are examples of transversal lines in the real world?
Transversal lines cut through or touch parallel lines as for example support sleepers on a rail track or transversal supports on a gate
What are lines opposite of the transversal lines?
Either parallel lines or longitudinal lines are opposite transversal lines.
Tell the difference between transversal lines and parallel lines?
The transversal is the line that cuts the parallel line.
What are transversal and corresponding angles?
A transversal line cuts through parallel lines forming equal corresponding angles
If two lines are cut by a transversal so that corresponding angles are congruent?
If two parallel lines are intersected by a transversal, then the corresponding angles are congruent. This is the transversal postulate. So the answer is the lines would be parallel. This means that the statement is true.
What is CACP postulate?
Given two lines cut by a transversal, if corresponding angles are congruent, then the lines are parallel.
Is it true that if two lines are crossed by a transversal the two lines are parallel?
A transversal is simply any line that passes through two or more coplanar lines each at different points. So picture, if you will, two lines that are clearly not parallel. I can easily construct a transversal that passes through them. HOWEVER, if two parallel lines are intersected by a transversal, then the corresponding angles are congruent. This is called the transversal postulate. If the corresponding angles are congruent, than the lines are parallel. This is the converse of the first postulate. So, the answer to your question is NO, unless the corresponding angles are congruent.
What is CACP postulate and examples of this?
Given two lines cut by a transversal, if corresponding angles are congruent, then the lines are parallel.
What is the linear pair postulate?
1. Where the angles in a linear pair are supplementry, and if parallel lines are cut by a transversal, then the interior angles are congruent, and if two lines are cut by a transversal so that a pair of alternate interior angles are congruent, then the two lines are parallel. That's what makes up a linear pair postulate anyway. 2. If two adjacent angle's unshared sides form a straight angle, then they are a linear pair. 3.If two angles form a linear pair,then they are supplementary.
What are transversal contracts?
transversal contract
A transversal creates pairs of?
transversal creates pairs of
What is the circumference of a transversal?
A transversal is a straight line and so it has no circumference.
What is a angle cut but a transversal?
What is a angle on the opposite side of the transversal
What is the same-side interior angles postulate?
Technically this does not exist. Many math texts use it as a shortcut to introduce properties of angles for parallel lines that are cut by a transversal. It says that when lines are parallel and are cut by a transversal, then the same side interior angles must be supplementary (add up 180 degrees). Once you say this is a postulate (assumed to be true), then you can prove other things like the Congruent Corresponding Angles theorem that says "If lines are parallel and are cut by a transversal, then the corresponding angles must be conguent." Some texts do the reverse and say Corresponding Angles is a postulate and then prove Same-Side Interior as a Theorem. Euclid proved both these using his 5th Postulate (often re-written as the Parallel Postulate or Playfair's Axiom). To do this, he had to prove that the interior angles of a triangle sum to 180. Since many Math Texts do not introduce this fact until later chapters, they take this shortcut of "assume the Same-Side Interior" is true and the remaining theorems are much easier. Another reason Math books may take this shortcut is that Euclid's method is usually done by proof by contradiction - which is sometimes more difficult to understand. I believe the Khan Academy video of this material is done correctly.
What is a transversal angle?
A Transversal angle is a line that intersects a system of lines.
What is a transversal?
A transversal is a line that crosses more than one line.
