2. Objectives
To identify any quadrilateral, by name, as specifically as you can, based on its characteristics

3. Quadrilateral
a quadrilateral is a polygon with 4 sides.

4. Specific Quadrilaterals
There are several specific types of quadrilaterals. They are classified based on their sides or angles.

6. A quadrilateral simply has 4 sides – no other special requirements.

7. Examples of Quadrilaterals

8. A parallelogram has two pairs of parallel sides.

9. Parallelogram Two pairs of parallel sides
opposite sides are actually congruent.

10. A rhombus is a parallelogram that has four congruent sides.

12. A rectangle has four right angles.

13. Rectangle
Still has two pairs of parallel sides; with opposite sides congruent.
Has four right angles

14. A square is a specific case of both a rhombus AND a rectangle, having four right angles and 4 congruent sides.

15. Square Still has two pairs of parallel sides. Has four congruent sides
Has four right angles

16. A trapezoid has only one pair of parallel sides.

17. An isosceles trapezoid is a trapeziod with the non-parallel sides congruent.

19. An kite is a quadrilateral with NO parallel sides but 2 pairs of adjacent congruent sides.
