If the transversal intersects the two parallel lines each pair of co-interior angles sums up to 180 degrees supplementary angles. Co-interior Angle Theorem and Proof.

### They are interior between the parallel lines and they are on the same side of the transversal.

**Same-side interior angles**. The largest interior angle and side are opposite each other. Let us consider the image given above. If two parallel lines are cut by a transversal then the same side interior angles are supplementary.

The co-interior angle is also known as the consecutive interior angles or the same side interior angles. If the two lines are parallel then the alternate interior angles are congruent. Two lines are said to be parallel when they have the same slop.

1 Same Side Interior Angles Theorem. Conversely if a transversal intersects two lines such that a pair of same side interior angles are supplementary then the two lines are parallel. When the lines are parallel the interior angles on the same side of the transversal are supplementary.

M1 m2 180 m3 m4 180. 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. In the figure angles 3.

A transversal line is a straight line that intersects one or more lines. If two parallel lines are cut by a transversal then the same side interior angles are supplementary. 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.

Alternate interior angles are angles that are on the inside of the two lines and on the opposite sides of the transversal. Two consecutive interior angles are 2x 10 and x 5. In the above figure the pairs of co-interior angles are.

Same Side Interior angles are the angle pairs that are on the insides of the two lines the interior and on the same side of the transversala experior angle of a triangle is to the 2 opposit. Then the value of the other pair of alternate interior angles is. So if and both are cut by then and.

Learn how to solve for an unknown variable using parallel lines and a transversal theorems. Theorem 64 If a transversal intersects two parallel lines then each pair of interior angles on the same side of the transversal is supplementary. If two parallel lines are cut by a transversal then the same side interior angles are supplementary.

What is a transversal line you may wonder. Co-interior angles are the pair of non-adjacent interior angles that lie on the same side of the transversal. The pairs of angles on one side of the transversal but inside the two lines are called Consecutive Interior Angles.

We know that same side interior angles are supplementary so their measures add up to 180. The same rule applies to the smallest sized angle and side and the middle sized angle and side. Same Side Interior Angles Theorem.

These angles are located exactly as their name describes. 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. If a transversal intersects two parallel lines each pair of same side interior angles are supplementary their sum is 180.

Relationship between measurement of the sides and angles in a triangle. Consecutive interior angles are supplementary. Since angles formed on the same side of the transversal are supplementary angles.

And are same side interior angles. The same side interior angle theorem states. The same-side interior angles are two angles that are on the same side of the transversal line and in between two intersected parallel lines.

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 can be recognized by being between two parallel lines and on the same side of the transversal. The angle pairs are Consecutive they follow each other and they are on the Interior of the two crossed lines.

1 and 4 2 and 3. Just like the exterior angles the four. In this example these are Consecutive Interior Angles.

When two parallel lines are intersected by a transversal same side interior between the parallel lines and same side exterior outside the parallel lines angles are formed. Find measure of the angles. Same-side interior angles are a pair of angles on one side of a transversal line and on the inside of the two lines being intersected.

Since alternate interior and alternate exterior angles are congruent and since linear pairs of angles are supplementary same side angles are supplementary. 180 0 121 0 59 0. To help you remember.
