supplementary
If two parallel lines are cut by a transversal, the sum of the measures of the interior angles on the same side of the transversal is 180 degrees. This is due to the properties of parallel lines and the angles formed by the transversal, which create corresponding and consecutive interior angles. Hence, these angles are supplementary.
When non-parallel lines are cut by a transversal, alternate interior angles are not necessarily equal. Instead, the relationship between these angles depends on the specific measures of the angles formed by the transversal and the non-parallel lines. Therefore, unlike the case with parallel lines, alternate interior angles do not have a consistent property of being congruent when the lines are not parallel.
a transversal line If a transversal intersects two parallel lines, then the alternate interior angles are congruent.
Parallel lines cut by a transversal form congruent alternate interior angles.
Alternate interior angles are equal on a transversal that passes through parallel lines.
a transversal line If a transversal intersects two parallel lines, then the alternate interior angles are congruent.
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.
Parallel lines cut by a transversal form congruent alternate interior angles.
Alternate interior angles are equal on a transversal that passes through parallel lines.
a transversal line If a transversal intersects two parallel lines, then the alternate interior angles are congruent.
Only if the lines cut by the transversal are parallel.
Remote interior angles and remote exterior angles.
Angles on opposite sides of the transversal and between the parallel lines
Congruent
They are if parallel lines are cut by a transversal that's perpendicular to them.
Sure. Just as long as the transversal is perpendicular to the parallel lines.
Co-interior angles are not congruent. The only case in which they would be is if the transversal was perpendicular to the two parallel lines.
