1. Let's clarify the problem: You want to know if two angles are co-interior angles. 2. Co-interior angles are pairs of angles on the same side of a transversal cutting through two lines. 3. The key property: If the two lines are parallel, co-interior angles add up to 180 degrees. 4. To check if two angles are co-interior, identify if they lie on the same side of the transversal and between the two lines. 5. If yes, and if the sum of their measures is 180 degrees, then they are co-interior angles. 6. Without specific angle measures or a diagram, we cannot definitively say if they are co-interior. 7. If you provide angle values or a figure, we can verify using the sum property: $$\text{angle}_1 + \text{angle}_2 = 180^\circ$$
