- 3. angles congruence theorem/ all right angles are congruent.
- 4. exterior angles converse/ if two lines are cut by a transversal so the aternate exterior angles are congruent, then the lines are parallel.
- 7. interior angles converse/ if two lines are cut by a transversal so the consecutive interior angles are supplimentary, then the lines are parallel.
- 9. angles theorem/ if two angles of one triangle are congruent to two angels of another angle, then the third angle is also congruent.
- 10. bisector theorem/ if a point is on the bisector of an angle, then it is equidistant from the two sides of the angle.
- 15. congruence/ if two sides and the included angle of one triangle are congruent to two sides and the included angle of a second triangle , then the two triangles are congruent.
- 18. Postulate/ if there is a line and a point not on the line, then there is exactly one line through the point parallel to the given line.
- 19. theorem/ if two sides of one triangle are congruent to two sides of another triangle, and the included angle of the first is larger than the angle of the second, then the included angle is larger than the third side of the second.
- 20. congruence/ if two angles of one triangle are congruent to two angles and the included side o a second triangle, then the two triangles are congruent.
- 21. compliments theorem/ if two angles are complimentatry to the same angle, then the two angles are congruent.
- 22. Angles Converse/ if two lines are cut by a transversal so the corresponding angles are congruent, then the lines are parallel.
- 23. Congruence/ if three sides of one triangle are congruent to three sides of a second triangle, then the two triangles are congruent.
- 26. of the Angle bisector theorem/ if a point is in the the interior of an angle and is equidistant from the sides of the angles, then it lies on the bisector of the angle.
- 27. theroem/ in the right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the length of legs.
- 29. Pair Postulate/ if two angles form a linear pair, then they are suplimentary.
- 30. Angles Congruence theorem/ vertical angles are congruent.
Down
- 1. mean/ in a right triangle , the altitude from the right angle to the hypotenuse divides the hypotenuse into two segments.
- 2. sum theorem/ the sum of the measures of the interior angles of a triangle is 180 degress.
- 5. property of parallel lines/ if two lines are parallel to eachother, then they are parallel to eachother.
- 6. of Angles Congruence/ angle congruence is reflexive, symmetric, and transitive.
- 8. interior angles theorem/ if two lines are cut by a transversal, then the pairs of consecutive interior angles are supplementary.
- 10. congruence theorem/ if two angles and a non included side of one triangle are congruent to two angles and the corresponding non included side of a second triangle, then the two triangles are congruent.
- 11. angles theorem/ if two sides of a triangle are congruent, then the angles opposite them are congruent.
- 12. similarity Postulate/ if two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar.
- 13. theorem/ the segment connecting the midpoints of two sides of a triangle is parrallel to the third side and is half as long as that side.
- 14. Postulate/the points on a line can be matched one to one with the real numbers. the real number corresponds to a point is the coordinate of the point
- 16. addition Postulate/ the area of a region is the sum of the areas of its nonoverlapping parts
- 17. of Perpendicular Lines/ in a coordinate plane, two nonvertical lines are perpendicular if and only if their slopes are -1.
- 18. bisector theorem/ if a point is on a perpencicular bisector of a segement, then it is equiedstant from the endpoints of the segment.
- 24. Addition Postulate/ if B is between A and C, then AB+BC=AC, then B is between A and C.
- 25. angle theorem/ the measure of an exterior angle of a triangle is equal to the sum of the measures of the two nonadjacent interior angles.
- 28. Congruence theorem/ if the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and a leg of a second right triangle, then the two triangles are congruent.
