Th long, long transversals
Description: Angles of a parralel and transversal lines
Image copyright: My on creation with paint
1. transversal- A line that crosses two or more lines.
2. Angle- The degree of two lines meeting at a certain point.
3. Parallel-Lines that never cross.
4. Perpendicular-Right angles that intersect.
5. Adjacent angle-Angles that are right next to each other.
6. Alternate exterior angle-parallel lines that intersect on the outside.
7. Alternate interior angle-parallel lines that intersect on the inside.
8. Vertical angle-A vertical angle is perpendicular to the horizon
9. Acute angle- An angle less than 90°
10. Obtuse angle-An angle bigger than 90°
11. Right angle- An angle that is 90°
