The false statement is angle 1 and angle 8 are alternate interior angles. ( option C)
When parallel lines intersected by a transversal, corresponding angles are equal, alternate angles are equal, and consecutive interior angles add up to 180 degrees.
These relationships are fundamental in geometry and solve various problems involving parallel lines.
In the diagram;
1. angle 2 and 6 are corresponding angles
2. angle 4 and 5 are alternate interior angles
3. angle 1 and 8 are alternate exterior angles
4. angle 1 and 4 are vertical angles
Therefore, the false statement is angle 1 and angle 8 are alternate interior angles.
