1. transversal- A line that goes through two or more other lines.
2. angle- The amount of turning between two lines that intersect.
3. parallel- Two lines that lie in the same coordinate plane but do not intersect.
4. perpendicular- When two lines intersect in a 90* or right angle.
5. adjacent angle- Next to each other.
6. alternate exterior angle- When a group of Parallel lines intersects with a transversal.
7. alternate interior angle- When a group of Parallel lines intersects with a transversal.
8. vertical angle- A line that goes up and down.
9. acute angle- An angle less than 90*.
10. obtuse angle- An angle greater than 90*.
11. right angle- An angle with a measure of 90*.
Key:
1. parallel lines-AC & E
2. transversal line- BF
3. adjacent angle(8)-1,2&2,3&3,4&4,1&8,5&5,6&6,7&7,8
4. alternate exterior angle(2)-4,5&1,6
5. alternate interior angle(2)-2,7&3,8
6. vertical angle(4)-2&4,1&3,5&7,6&8
7. acute angle-6,8&2,4
8. obtuse angle-1,3,5,7
9. right angles, if any-0
