If The Angles Are Consecutive Interior, How Do I Find X?

The ‘consecutive interior angle theorem’ states that if a transversal intersects two parallel lines, each pair of consecutive interior angles is supplementary, meaning the sum of the consecutive interior angles is 180°. This is particularly true when two lines are crossed by another line, known as the transversal. In this example, the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles.

The consecutive interior angles are ∠Y and ∠A, ∠Z and ∠B, and ∠W + ∠X = 180°. They form pairs of consecutive interior and exterior angles, with ∠3 and ∠5; ∠4 and ∠6. Pairs of consecutive exterior angles are ∠1 and ∠7; ∠2 and ∠8.

Consecutive interior angles can be defined as two interior angles lying on the same side of the transversal cutting across two parallel lines. To prove the theorem, use the axiom of parallel lines and the corresponding angles.

In the given pairs of consecutive interior angles, find the value of x and the magnitude of a consecutive interior angle. Consecutive internal angles are pairs of non-adjacent interior angles located on the same side of the transversal.

In conclusion, the ‘consecutive interior angle theorem’ states that if two parallel lines intersect a transversal, each pair of consecutive interior angles is supplementary, meaning they add up to 180°.
