## When lines are parallel same side interior angles are?

Same side interior angles are congruent when lines are parallel.

## How do you prove parallel lines with the same side interior angles?

Apply the Same-Side Interior Angles Theorem in finding out if line A is parallel to line B. The theorem states that the same-side interior angles must be supplementary given the lines intersected by the transversal line are parallel. If the two angles add up to 180°, then line A is parallel to line B.

**When parallel consecutive interior angles are?**

When the two lines being crossed are Parallel Lines the Consecutive Interior Angles add up to 180°.

### What is interior angle test for parallel lines?

The Alternate Interior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent . So, in the figure below, if k∥l , then ∠2≅∠8 and ∠3≅∠5 .

### What are same side interior angles called?

Same side interior angles are on the same side of the transversal. Same side interior angles are congruent when lines are parallel.

**Which pair of angles is an example of consecutive interior angles?**

When two lines are cut by a transversal, the pair of angles on one side of the transversal and inside the two lines are called the consecutive interior angles. In the figure, the angles 3 and 5 are consecutive interior angles.

#### How do you prove lines are parallel?

If two lines are cut by a transversal so the alternate exterior angles are congruent, then the lines are parallel. If two lines are cut by a transversal so the consecutive interior angles are supplementary, then the lines are parallel. If two lines are parallel to the same line, then they are parallel to each other.

#### What are examples of interior angles?

Interior Angle. An angle on the interior of a plane figure. Examples: The angles labeled 1, 2, 3, 4, and 5 in the pentagon below are all interior angles.

**What is the same side interior theorem?**

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. 0.0.

## What do same side interior angles equal?

The sum of same-side interior angles is equal to 180 degrees. A transversal line is a line that intersects other lines. Parallel lines are lines that run alongside each other that never intersect.

## What is the definition of same side exterior angles?

Same Side Exterior Angles. Definition: Same-side exterior angles are a pair of angles formed by two lines and a transversal and are located on the same side of the transversals and outside (on the exterior of) the two lines. 1 and 8 are same-side interior angles.
