Study Notes
- Lines that are in the same direction and will never cross are called 'parallel lines'.
- When lines cross at a point, it's called an 'intersection', and angles are formed.
- Angles can be named using the points that form them, and arcs can represent angles between intersecting lines.
- Perpendicular lines form right angles, which are indicated by a special square symbol.
- An acute angle is smaller than a right angle, while an obtuse angle is larger.
- A straight angle is formed by two rays pointing in opposite directions, creating a straight line.
- Complementary angles combine to form a right angle, while supplementary angles combine to form a straight angle.
