- A right angle is 90 degrees and is represented by a square angle notation. Acute angles are less than 90 degrees and obtuse angles are greater than 90 degrees but more than 180 degrees.
- Straight lines are equal to 180 degrees.
- Reflex angles are greater than 180 degrees but less than 360 degrees.
- Angles around a point or in a circle add up to 360 degrees.
Angles in parallel lines:
- Parallel lines are always the same distance apart and never meet.
- When a pair of parallel lines is cut with another line, known as an intersecting transversal, pairs of angles with special properties are created:
- Angles that make F shapes are corresponding angles and are equal.
- Angles that make Z shapes are alternate angles and are equal.
