Proofs Geometry

2. If 3(x + 3)=6, then 3x + 9=6
6. Divides the segment into two congruent parts
8. A step in the process of solving an equation for a proof
12. If two angles are supplemental, then they are congruent
15. a=a, a value will always equal itself
17. An angle that is exactly 90 degrees, often made up of complementary angles
18. a line, segment, or plane, that goes through the midpoint of a segment
19. Proof that is used to solve angles
20. Proof that is used to solve algebraic equations.
22. If two angles are complemental, then they are congruent
24. If 12a=3b, then 4a=b
25. Proof that is used to solve a type of equation
26. If x=y, then y=x

1. If a=b+c and d=c, then a=b+d
3. If 3b=2a - b, then 4b=2a
4. A value or equation that you start with and use to solve the equation
5. An angle that can be 1-89 degrees. CAN be complementary.
7. If a=b and b=c then a=c
9. a line that connects multiple points and endpoints
10. An angle that is exactly 180 degrees, often made up of supplementary angles
11. An angle that can be 91-179 degrees. Can NOT be complementary.
13. Line that divides something into 2
14. If and only if they have the same measure
16. If 3a=3b + a, 2a=3b
19. a ray, a plane, a line, or a segment that halves an angle
21. Two lines that intersect at an endpoint or ray
23. Proof that is used to solve segments
