**6.1 The Polygon-Angle Sum Theorems**

- Essential Understanding:
- The sum of the exterior angles of a polygon is 360 degrees, regardless of the number of sides. The sum of the interior angles of a polygon is 180(
*n*-2), where*n*is the number of sides.

**6.2 Kites and Trapezoids**

- Essential Understanding:
- Diagonals of a kite are perpendicular, and one diagonal bisects the other. In isosceles trapezoids, diagonals are congruent. The length of the midsegment of a trapezoid is half the sum of the base of the lengths.

**6.3 Properties of Parallelograms**

- Essential Understanding:
- In a parallelogram, consecutive angles are supplementary, opposite angles are congruent, opposite sides are congruent, and diagonals bisect each other.

**6.4 Proving a Quadrilateral is a Parallelogram -**

**Due to MALWARE ISSUES, please visit with Mrs. Moore to obtain copies of the notes and/or HW answer keys.**

- Essential Understanding:
- A quadrilateral with two pairs of congruent sides, or one pair of congruent parallel sides, or diagonals bisecting each other is a parallelogram. A quadrilateral with an angle supplementary to both of its consecutive angles, or two pairs of opposite congruent angles is a parallelogram.

**6.5/6.6 Properties and Conditions of Special Parallelograms -**

**Due to MALWARE ISSUES, please visit with Mrs. Moore to obtain copies of the notes and/or HW answer keys.**

- Essential Understandings:
- The diagonals of a rhombus are perpendicular, bisect each other, and bisect opposite angles. They form four congruent triangles. In a rectangle, the diagonals are congruent. Squares have properties of rhombuses
*and*rectangles. If a parallelogram has perpendicular diagonals or diagonals that bisect angles, then the parallelogram is a rhombus. If a parallelogram has congruent diagonals, then the parallelogram is a rectangle. If a parallelogram has perpendicular congruent diagonals, or if the parallelogram has congruent diagonals with a diagonal that bisects its angles, then the parallelogram is a square.
