linear pair conjecture
If two angles form a linear pair , then their angles always equal 180 degrees
vertical angles conjecture
If two angles are vertical angles , then they are congruent
corresponding angles conjecture
If two parallel lines are cut by a transversal, then corresponding angles are congruent
alternate interior angles conjecture
If two parallel lines afre cut by a transversal, than alternate exterior angles are supplementary
parallel lines conjecture
If two parallel lines are cut by a transversal, then corresponding angles are always equal to 180 degrees; alternate interior angles are complementary, and alternate exterior angles are supplementary
converse of the parallel lines conjecture
If two lines are cut by a transversal to form pairs of congruent corresponding angles, congruent alternate interior angles, or congruent alternate exterior angles then the lies are congruent
perpendicular bisector conjecture
If a point is on the perpendicular bisector of a segment , then it is equidistant from the endpoints
converse of the perpendicular bisector conjecture
If a point is equidistant from the endpoints of a segment , then it is on the bisector of the segment
shortest distance conjecture
the shortest distance from a point to a line is measures along the straight from the point to the line
angle bisector conjecture
If a point is on the bisector of an angle , then it is equidistant from the sides of the angles
SSS conjecture
If the three sides of one triangle are congruent to the three sides of another triangle, then the triangles are congruent
SAS conjecture
If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle , then the triangles are congruent
ASA conjecture
If two angles and the included side of one triangle are congruent to the two angles and the included side of another triangle , then the triangles are congruent
SAA conjecture
If two angles and a non-included side of one triangle are congruent to the corresponding angles and side of another triangle, then the triangles are congruent
