A parallelogram A parallelogram A parallelogram is a quadrilateral (four sides) A parallelogram is a quadrilateral (four sides) 1 A parallelogram is a quadrilateral (four sides) 1 2 A parallelogram is a quadrilateral (four sides) 3 1 2 A parallelogram is a quadrilateral (four sides) 4 3 1 2 A parallelogram has how many sides? A parallelogram is a quadrilateral (four sides) A parallelogram is a quadrilateral (four sides) with opposite sides parallel A parallelogram is a quadrilateral (four sides) with opposite sides parallel these are parallel A parallelogram is a quadrilateral (four sides) with opposite sides parallel and these are parallel Parallelograms have several properties Parallelograms have several properties opposite sides are equal Parallelograms have several properties opposite sides are equal Parallelograms have several properties opposite sides are equal 3 5 In parallelograms, opposite angles are also equal In parallelograms, opposite angles are also equal In parallelograms, opposite angles are also equal 130 50 The diagonals in parallelograms are bisected The diagonals in parallelograms are bisected The diagonals in parallelograms are bisected The diagonals in parallelograms are bisected The diagonals in parallelograms are bisected 8 4 Because opposite sides are parallel, Because opposite sides are parallel, Because opposite sides are parallel, Because opposite sides are parallel, same side interior angles (bracket) add to 180 Because opposite sides are parallel, same side interior angles (bracket) add to 180 Add to 180 Because opposite sides are parallel, same side interior angles (bracket) add to 180 Add to 180 Because opposite sides are parallel, same side interior angles (bracket) add to 180 Add to 180 Because opposite sides are parallel, same side interior angles (bracket) add to 180 Add to 180 110 Also, because opposite sides are parallel, Also, because opposite sides are parallel, alternate interior (Z shape) angles are congruent Also, because opposite sides are parallel, alternate interior (Z shape) angles are congruent Also, because opposite sides are parallel, alternate interior (Z shape) angles are congruent These two angles are equal Also, because opposite sides are parallel, alternate interior (Z shape) angles are congruent These two angles are equal Also, because opposite sides are parallel, alternate interior (Z shape) angles are congruent These two angles are equal Also, because opposite sides are parallel, alternate interior (Z shape) angles are congruent These two angles are equal 30 40 |
