Parallel lines form congruent alternate interior angles?
Parallel lines cut by a transversal form congruent alternate interior angles.
What is a line that intersects two parallel lines?
a transversal line If a transversal intersects two parallel lines, then the alternate interior angles are congruent.
What is meant by alternate Interior angles?
Alternate interior angles are equal on a transversal that passes through parallel lines.
If two lines are cut by a transversal to form pairs of congruent corresponding angles congruent alternate interior angles or congruent alternate exterior angles then what are the lines?
The lines are parallel. The only time you will see correpsonding, alternate interior, and alternate exterior angles is with a parallel transversal line.
Can alternate interior angles be supplementary?
They are if parallel lines are cut by a transversal that's perpendicular to them.
Parallel lines form congruent alternate interior angles?
Parallel lines cut by a transversal form congruent alternate interior angles.
What is a line that intersects two parallel lines?
a transversal line If a transversal intersects two parallel lines, then the alternate interior angles are congruent.
What is meant by alternate Interior angles?
Alternate interior angles are equal on a transversal that passes through parallel lines.
What is a line that intersects parallel lines?
a transversal line If a transversal intersects two parallel lines, then the alternate interior angles are congruent.
Are alternate interior angles congruent?
Only if the lines cut by the transversal are parallel.
If 2 parallel lines are cut by a transversal alternate interior angles are what?
When 2 parallel lines are cut by a transversal some of the pairs of angles which are formed are called alternate angles whereas other pairs are called interior angles.
If two lines are cut by a transversal to form pairs of congruent corresponding angles congruent alternate interior angles or congruent alternate exterior angles then what are the lines?
The lines are parallel. The only time you will see correpsonding, alternate interior, and alternate exterior angles is with a parallel transversal line.
If two parallel lines are cut by a transversal then the alternate interior angles are always?
Congruent
Can alternate interior angles be supplementary?
They are if parallel lines are cut by a transversal that's perpendicular to them.
Can all alternate interior and corresponding angles formed by two parallel lines and a transversal be congruent?
Sure. Just as long as the transversal is perpendicular to the parallel lines.
What does alternate interior angle mean?
Alternate int angles are two interior angles which lie on different parallel lines and on opposite sides of a transversal
How many pairs of alternate interior angles are formed by two lines that are intersected by a transversal?
Providing that the lines are parallel that the transversal passes through then it will have two equal alternate angles that are on opposite sides of the transversal.
