In a coordinate plane, parallel Lines are lines that do not meet or intersect. They are always the same distance apart. Moreover, parallel lines have the same slope.

We can visualize an angle as the figure formed when two line segments share a common endpoint. We can also think about an angle as a measure of rotation. A full rotation or a full circle is 360∘ , so a half rotation or U-turn is 180∘ , and a quarter turn is 90∘ .
