## What do alternate interior angles add up to?

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 is alternate interior and exterior angles?

Angles that are in the area between the parallel lines like angle 2 and 8 above are called interior angles whereas the angles that are on the outside of the two parallel lines like 1 and 6 are called exterior angles . Angles that are on the opposite sides of the transversal are called alternate angles e.g. 1 + 8.

## How do you find alternate angles?

One way to identify alternate exterior angles is to see that they are the vertical angles of the alternate interior angles . Alternate exterior angles are equal to one another. When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent.

## What do alternate interior angles look like?

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.

## What do same side interior angles look like?

Same side interior angles are two angles that are on the same side of the transversal and on the interior of (between) the two lines. Same Side Interior Angles Theorem: If two parallel lines are cut by a transversal, then the same side interior angles are supplementary.

## 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 .

## What are the properties of alternate angles?

What Are The Properties of Alternate Interior Angles? Alternate Interior angles are congruent. The sum of the angles formed on the same side of the transversal which are inside the two parallel lines is equal to 180°. Alternate interior angles don’t have any specific properties, in case of non-parallel lines.

## Do alternate interior angles have the same measure?

Alternate Interior Angles are created where a transversal crosses two (usually parallel) lines. Each pair of these angles are inside the parallel lines, and on opposite sides of the transversal. Notice that the two alternate interior angles shown are equal in measure if the lines PQ and RS are parallel.

## What are alternate angles with diagram?

Alternate angles are angles that are in opposite positions relative to a transversal intersecting two lines. Examples. If the alternate angles are between the two lines intersected by the transversal, they are called alternate interior angles . In each illustration below, LINE 1 is a transversal of LINE 2 and LINE 3.

## Do same side interior angles add up to 180?

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.

## Why are alternate interior angles always congruent?

Alternate Interior Angle Theorem The Alternate Interior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent .

## What is the definition of alternate angles?

two nonadjacent angles made by the crossing of two lines by a third line, both angles being either interior or exterior, and being on opposite sides of the third line.

## How do you find interior angles?

Alternate interior angles are formed when a transversal passes through two lines. The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles . The theorem says that when the lines are parallel, that the alternate interior angles are equal.
