Classify the relationship between angle two and angle six as alternate interior, alternate exterior, corresponding, or consecutive interior angles.

Let’s think about what we know. If we have two lines cut by a transversal, alternate interior angles are on opposite sides of the transversal but inside the two lines. Alternate exterior lines [angles] are on opposite sides of the transversal and outside the two lines. Corresponding angles are in matching corners. For example, these are both in the top-left corner. And consecutive interior angles are on the same side of the transversal and on the inside of the two lines.

Now, we need to check and see which relationship best describes angle two and angle six, these angles. Angle two and angle six are on opposite sides of the transversal, and they’re on the inside of the two lines, making them alternate interior angles.
