Angles ∠1 and ∠7 are alternate interior angles and angle ∠4 and ∠8 are adjacent angles.
What are lines and angles?
Lines are straight with little depth or width. Perpendicular lines, intersecting lines, transversal lines, and other types of lines will be covered. An angle is a shape formed by two rays emerging from a common point. In this field, you may also come across alternate and equivalent angles.
The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
When a transversal connects two coplanar lines, alternate interior angles are generated. They are on the inside of the parallel lines, but on the outside of the transversal.
