When parallel lines are cut by a transversal alternate interior angles are?

When parallel lines are cut by a transversal alternate interior angles are?

congruent
If two parallel lines are cut by a transversal, then, Alternate Interior Angles are congruent.

When two parallel lines are cut by a transversal how many angles are formed?

eight angles
When two parallel lines are intersected by the transversal, eight angles are formed. The eight angles include corresponding angles, alternate interior and exterior angles, vertically opposite angles, and co-interior angles.

When two lines are cut by a transversal if the alternate interior angles are equal in measure then the lines are parallel quizlet?

If a transversal intersects two lines in such a way that a pair of alternate interior angles are equal, then the two lines are parallel. when two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent.

When two parallel lines are cut by a transversal interior angles are supplementary?

If two parallel lines are cut by a transversal, the interior angles on the same side of the transversal are supplementary. If two lines are cut by a transversal and the interior angles on the same side of the transversal are supplementary, the lines are parallel.

Which pair of angles are alternate interior angles?

When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These angles are always equal.

Which angles are alternate interior angles?

the angles which are inside the parallel lines and on alternate sides of the third line are called alternate interior angles. If two parallel lines are transected by a third line, the angles which are on the same side of the third line and on corresponding sides of the parallel lines are called corresponding angles.

What are alternate interior angles?

the angles which are inside the parallel lines and on alternate sides of the third line are called alternate interior angles. If two parallel lines are transected by a third line, the angles which are inside the parallel lines and on the same side of the third line are called opposite interior angles.

When two lines are cut by a transversal select the angles that are supplementary?

When two lines are cut by a transversal, the pairs of angles on one side of the transversal and inside the two lines are called the consecutive interior angles . If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles formed are supplementary .

When the lines are parallel the alternate interior angles?

The Alternate Interior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent .

What are the 2 pairs of alternate interior angles?

The term alternate interior angles is often used when two lines are cut by a third line, a transversal .

• In the figure above, line t is a transversal cutting lines k and l , and there are two pairs of alternate interior angles:
• ∠2 and ∠8.
• ∠3 and ∠5.

What are the pairs of alternate interior angles?

Therefore, the pairs of alternating interior angles are:

• ∠a & ∠ d.
• ∠b & ∠
