Angles

1. lines planes that do NOT intersect
4. triangle a triangle that has at least two congruent sides
6. triangle a triangle whose sides are all congruent
7. pair a pair of adjacent angles whose non - common sides are opposite rays. The angles of a linear pair form a straight angle
9. side interior angles interior angles that lie on the side of the transversal
11. angles two angles whose measures have a sum of 90 degrees. each angles Is called the complement of the other.
12. an accepted statement of fact
13. a conclusion reached by using inductive reasoning
14. Angles The angles whose measures have a sum of 180 degrees. each angle is called the supplement of the other
16. angles two coplanar angles with a common side, a common vertex, and no common interior points.
18. the statement contained by reversing the hypothesis and conclusion of a conditional
19. triangle a triangle that has no congruent sides

2. interior angles non adjacent interior angles that lie on opposite sides of the transversal
3. lines two lines that intersect right angles
5. a conjecture that is proven
8. angles angle's that lie on the same side of the transversal and in corresponding positions
10. lines non - coplanar ; they are not parallel and do not intersect
11. example an example showing that a statement is false
15. a line that intersects two or more coplanar lines at distinct points
17. angles two angles whose sides are opposite rays
