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.

What is always true about alternate interior angles when non-parallel lines are cut by a transversal?

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.


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 happens when parallel lines are cut by a transversal?

When parallel lines are cut by a transversal, several angles are formed that have specific relationships. Corresponding angles are equal, alternate interior angles are equal, and consecutive interior angles are supplementary (adding up to 180 degrees). These properties are fundamental in geometry and help in solving problems related to angle measures and relationships in parallel lines.


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 is two angles that are formed by two lines and a transversal that lie outside the two lines and on the same side of the tranversal?

When a transversal line cuts through two parallel lines supplementary angles are created that add up to 180 degrees

What is A line that cuts two parallel lines?

A line that cuts two parallel lines is called a transversal. When a transversal intersects two parallel lines, it creates several angles, including corresponding angles, alternate interior angles, and consecutive interior angles, which have specific relationships and properties. These relationships are often used in geometry to prove the parallelism of lines or to solve for unknown angle measures.
