5. Lines p and q are parallel, and line w is a transversal. Which angle is not congruent to angle 1?

Answer:
∠2, ∠4, ∠6 and ∠8 are not congruent to ∠1.
Step-by-step explanation:
From the picture attached,
p and q are the parallel lines and w is a transversal.
∠1 ≅ ∠3 [Vertically opposite angles]
∠1 ≅ ∠5 [Corresponding angles]
∠1 ≅ ∠7 [Alternate exterior angles]
Therefore, ∠2, ∠4, ∠6 and ∠8 are not congruent to ∠1.
