Do same side interior angles have the same measure?
Same – side interior angles are NOT always congruent. In fact, the only time they are congruent (meaning they have the same measure ) is when the
What are the alternate interior angles?
Alternate Interior Angles are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal. In this example, these are two pairs of Alternate Interior Angles : c and f.
Are 180 interior angles the same side?
The same – side interior angle theorem states that when two lines that are parallel are intersected by a transversal line, the same – side interior angles that are formed are supplementary, or add up to 180 degrees.
What are interior angles on the same side of the transversal called?
When the lines are parallel, the interior angles on the same side of the transversal are supplementary. If two parallel lines are cut by a transversal , the interior angles on the same side of the transversal are supplementary.
What are alternate angles simple definition?
: one of a pair of angles with different vertices and on opposite sides of a transversal at its intersection with two other lines: a : one of a pair of angles inside the two intersected lines. — called also alternate interior angle .
What is the difference between alternate interior angles and consecutive interior angles?
If they are on the same side, then the angles are considered consecutive . If they are on opposite sides, then the angles are considered alternate . Are the angles inside or outside of the two intersected lines? If they are inside the two lines, then they will be classified as interior .
Do alternate interior angles have to be congruent?
Alternate interior angles are congruent . Consecutive interior angles are supplementary. Consecutive interior angles are interior angles which are on the same side of the transversal line. Alternate interior angles don’t have any specific properties in the case of non – parallel lines.
What happens if a transversal intersects two parallel lines?
If a transversal intersects two parallel lines , then alternate interior angles are congruent. If a transversal intersects two parallel lines , then same-side interior angles are supplementary. If two lines and a transversal form corresponding angles that are congruent, then the two lines are parallel .
