## Can same side interior angles be equal?

The same side interior angles are NOT congruent. They are supplementary. The same side interior angles can be congruent only when each angle is equal to a 90 degree because then the sum of the same side interior angles is equal to 180 degrees.

**Are same side interior angles equal or supplementary?**

The same-side interior angles theorem states that same-side interior angles are supplementary when the lines intersected by the transversal line are parallel. 2) Since the lines A and B are parallel, the same-side interior angles theorem states that same-side interior angles will be supplementary.

### Do same side interior angles add up to 90?

Same side interior angles are always supplementary, meaning that the sum of their measures if 180°. We have 90 plus the same side interior angle which is 3x and we end up with 180.

**Do same alternate interior angles add up to 180?**

Alternate angles are equal. d and f are interior angles. These add up to 180 degrees (e and c are also interior). Any two angles that add up to 180 degrees are known as supplementary angles.

#### What do alternate interior angles look like?

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. Here AB and CD are two parallel lines crossed by a transversal.

**What is the difference between alternate interior angles and consecutive interior angles?**

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 is alternate interior angles example?

The term alternate interior angles is often used when two lines are cut by a third line, a transversal . The Alternate Interior Angles Theorem states that if k and l are parallel , then the pairs of alternate interior angles are congruent . That is, ∠2≅∠8 and ∠3≅∠5 .

**How many interior angles are on the same side?**

The same-side interior angles sum up to 180 degrees. When two parallel lines are intersected by a transversal line they formed 4 interior angles. The 2 non-adjacent interior angles that are on the same side of the transversal are supplementary. 1. What Are Same Side Interior Angles?

### Are there any angles that are not equal to each other?

Co-interior angles resemble like in “C” shape and both the angles are not equal to each other. The co-interior angle is also known as the consecutive interior angles or the same side interior angles.

**Which is an example of a co interior angle?**

The co-interior angle is also known as the consecutive interior angles or the same side interior angles. If the transversal intersects the two parallel lines, each pair of co-interior angles sums up to 180 degrees (supplementary angles). In the figure, angles 3 and 5 are the co interior angles and angles 4 and 6 are the co-interior angles.

#### Which is the best definition of alternate interior angles?

1 Antithesis of Theorem. If the alternate interior angles produced by the transversal line on two coplanar are congruent, then the two lines are parallel to each other. 2 Co-interior Angles. Co-interior angles are the two angles that are on the same side of the transversal. 3 Co-interior Angle Theorem and Proof. 4 Examples.
