When two lines are crossed by another line (called the Transversal): The pairs of angles on one side of the transversal but inside the two lines are called Consecutive Interior Angles. In this example d and f …

The 'consecutive interior angle theorem' states that if a transversal intersects two parallel lines, each pair of consecutive interior angles is supplementary, that is, the sum of the consecutive interior angles is …

What are same side interior angles? Same side interior angles, also known as consecutive interior angles or co-interior angles, are pairs of angles that are on the same side of a transversal line and …

Oct 16, 2025 · Consecutive interior angles are pairs of angles on one side of a line—called a “transversal”—that crosses two other lines. The Consecutive Interior Angle Theorem states that …

Dec 12, 2025 · So, if two angles sit next to each other on the same side of the transversal, they are considered consecutive. This all leads us to the following conclusions: the pair ∠ c and ∠ e are …

Consecutive interior angles are formed when a transversal crosses two parallel lines. These angles exist on the same side of the transversal and inside the space between the two lines. Each pair of …

Consecutive interior angles are a pair of angles that are located on the same side of the transversal and are in between the two lines it intersects. They are also commonly known as co-interior angles or …
