For any angle, the measure of the whole is equal to the sum of the measures of its non- overlapping parts

If two angles form a linear pair, then they are supplementary.

If two angles are supplements of the same angle, then they are congruent.

If two angles are complements of the same angle, then they are congruent.

All right angles are congruent.

Vertical angles are equal in measure

For any segment, the measure of the whole is equal to the sum of the measures of its non-overlapping parts

If two parallel lines are intersected by a transversal, then the corresponding angles are equal in measure

If two lines are intersected by a transversal and corresponding angles are equal in measure → the lines are parallel

If two parallel lines are intersected by a transversal, then alternate interior angles are equal in measure

If two parallel lines are intersected by a transversal, then alternate exterior angles are equal in measure

If two parallel lines are intersected by a transversal, then same-side interior angles are supplementary.

If two lines are intersected by a transversal and alternate interior angles are equal in measure, then the lines are parallel

If two lines are intersected by a transversal and alternate exterior angles are equal in measure, then the lines are parallel

If two lines are intersected by a transversal and same-side interior angles are supplementary, then the lines are parallel

If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment

If a point is the same distance from both the endpoints of a segment, then it lies on the perpendicular bisector of the segment

In a coordinate plane, two nonvertical lines are parallel if and only then they have the same slope.
