  1. GEOMETRY: Chapter 8 8.2: Use Properties of Parallelograms

  2. If a quadrilateral is a parallelogram, then its opposite sides are congruent. Theorem 6.2: Image taken from: Geometry. McDougal Littell: Boston, 2007. P. 515.

  3. Theorem 6.3 If a quadrilateral is a parallelogram, then its opposite angles are congruent. Image taken from: Geometry. McDougal Littell: Boston, 2007. P. 515.

  4. Ex.1: Find the value of x and y. Images taken from: Geometry. McDougal Littell: Boston, 2007. P.516.

  5. Ex.1: Find the value of x and y. Answer: 72, 44 Images taken from: Geometry. McDougal Littell: Boston, 2007. P.516.

  6. Theorem 6.4 If a quadrilateral is a parallelogram, then its consecutive angles are supplementary. Images taken from: Geometry. McDougal Littell: Boston, 2007. P.516.

  7. Ex. 2: A metal screen is used to cover a shop window when the shop is closed. The sections of the screen are parallelograms. If the measure of angle LMN is equal 110o, what is the measure of angle MNO? Images taken from: Geometry. McDougal Littell: Boston, 2007. P.517.

  8. Ex. 2: A metal screen is used to cover a shop window when the shop is closed. The sections of the screen are parallelograms. If the measure of angle LMN is equal 110o, what is the measure of angle MNO? Answer: 70o Images taken from: Geometry. McDougal Littell: Boston, 2007. P.517.

  9. Theorem 6.5 If a quadrilateral is a parallelogram, then the diagonals bisect each other. Images taken from: Geometry. McDougal Littell: Boston, 2007. P.517.
