Question

which angle pair does not belong with the other three? explain they are formed by three lines intersecting in one point by four lines intersecting in one point by a transversal intersecting two coplanar lines at different points as alternate exterior angles

Explanation:

Step1: Analyze each angle pair

• For $\angle2$ and $\angle3$: They are adjacent angles formed by two intersecting lines.
• For $\angle4$ and $\angle5$: They are alternate - interior angles formed by a transversal intersecting two coplanar lines at different points.
• For $\angle1$ and $\angle8$: They are alternate - exterior angles formed by a transversal intersecting two coplanar lines at different points.
• For $\angle2$ and $\angle7$: They are alternate - exterior angles formed by a transversal intersecting two coplanar lines at different points.

Answer:

$\angle2$ and $\angle3$
