Theorem 6-1
Angles of a polygon that share a side are consecutive angles
Consecutive angles
Opposite sides of a parallelogram are congruent
Theorem 6-2
The diagonals of a parallelogram bisect each other
Theorem 6-3
If three or more parallel lines cut off congruent segments on one transversal then they cut off co great segments on every transversal
Theorem 6-4
If both pairs of opposite sides of a quadrilateral are congruent then the quadrilateral is a parallelogram
Theorem 6-5
If both pairs of opposite angles Ina quadrilateral are congruent then the quadrilateral is a parallelogram
Theorem 6-6
If one pair of a quadrilateral is both congruent and parallel then the quadrilateral is a parallelogram

Theorem 6-14
Two angles tht share a base of a trapezoid
Base angle
The base angles of an isosceles trapezoid are congruent
Theorem 6-15

Theorem 6-17
Segment that joins the midpoint of the non parallel opposite sides
Mid segment of trapezoid
The mid segment of a trapezoid is parallel to the bases and the length of the mid segment of a trapezoid is half the sum of the lengths of its bases
