A D B C Definition: Parallelogram with Four right angles. Diagonals are congruent. M

A D B C 1 Definition: Parallelogram with Four congruent sides. Diagonals are perpendicular. M Diagonals bisect opposite angles

A D B C Definition: It’s a Rectangle Rhombus M Rectangle& a Rhombus

Definition: Quadrilateral with exactly one pair of parallel sides. Bases are parallel. A D B C  A &  D are supp. and  B &  C are supp.

Midsegment: Segment that joins the midpoints of the legs of a trapezoid. XY is the midsegment. A D B C Midsegment is ll to bases and ½ measure of the sum of bases. XY

Definition: Trapezoid that has congruent legs. Legs are congruent. A D B C  A   B and  D   C. Each pair of Base angles are congruent. Diagonals are congruent:

Definition: Quadrilateral that has Two pair of congruent Adjacent sides and no opposite sides congruent. Diagonals are . B C D A One pair of opposite Angles are congruent.

B C D A One diagonal bisects the other. Pythagorean Theorem is often used to find measures.
