What else can I help you with?
Are alternate interior angles congruent?
Only if the lines cut by the transversal are parallel.
What is the converse of parallel lines conjecture?
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 the lines are parallel.
If alternate interior angels are congruent then the lines are?
Then the lines are parallel to each other and the alternate equal angles are created when a transversal line cuts through parallel lines.
Why is alternate interior angles similar to corresponding angles?
Because when a transversal line cuts through parallel lines it creates vertical opposite equal angles.
If two parallel lines are cut by a transversal then are the alternate interior angles always supplementary?
yes because they will always equal 180 degrees, regardless of the angle at which the transversal intersects the two parallel lines
What is meant by alternate Interior angles?
Alternate interior angles are equal on a transversal that passes through parallel lines.
Parallel lines form congruent alternate interior angles?
Parallel lines cut by a transversal form congruent alternate interior angles.
Are alternate interior angles congruent?
Only if the lines cut by the transversal are parallel.
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 a line that intersects parallel lines?
a transversal line If a transversal intersects two parallel lines, then the alternate interior angles are congruent.
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
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.
What is the definition for the word alternate interior angles?
Angles on opposite sides of the transversal and between the parallel lines
If alternate interior angles are congruent than lines are parallel what is it called?
It is the transversal line that cuts through parallel lines creating alternate equal angles.
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.
Alternate interior angle theorem?
The alternate interior angle theorem states that when two parallel lines are cut by a transversal, the alternate interior angles formed are congruent. In other words, if two parallel lines are crossed by a third line, then the pairs of alternate interior angles are equal in measure.
