2. 2. For your Notes:A quadrilateral has 4 sides and 4 angles.
7. 7. Quadrilaterals These arrows indicate the lines are parallel.
8. 8. Quadrilaterals These arrows indicate the lines are parallel.
9. 9. Quadrilaterals These arrows indicate the lines are parallel.
10. 10. Quadrilaterals Notice that these These arrows have 2 arrows to indicate the lines differentiate from are parallel. the other parallel lines.
11. 11. Quadrilaterals Notice that these These arrows have 2 arrows to indicate the lines differentiate from are parallel. the other parallel lines.
12. 12. Quadrilaterals Notice that these These arrows have 2 arrows to indicate the lines differentiate from are parallel. the other parallel lines.
13. 13. Quadrilaterals Notice that these These arrows have 2 arrows to indicate the lines differentiate from are parallel. the other parallel lines. These dashes represent the sides are equal in length

28. 28. The sides with only one The sides with two dash are equal in dashes are equal in length. length. 1. True 2. True 3. Parallelogram 4. Rhombus, Parallelogram 5. Rectangle, Parallelogram6. There should be no right angles, and the sides should not all be equal.
29. 29. Copy in your notes:Angles of a quadrilateral measure 360 degrees.
30. 30. Copy in your notes:Angles of a quadrilateral measure 360 degrees.
31. 31. EliminateA because the angle is Copy in obviously obtuse. your notes: Angles of a quadrilateral measure 360 degrees.
32. 32. EliminateA because the angle is Copy in obviously obtuse. your notes: Angles of a quadrilateral measure 360 degrees.
33. 33. EliminateAdd all the sides, A because the then subtract angle is from 360. Copy in obviously obtuse. your notes: Angles of a quadrilateral measure 360 degrees.
34. 34. EliminateAdd all the sides, A because the The correct then subtract angle is answer is B. from 360. Copy in obviously obtuse. your notes: Angles of a quadrilateral measure 360 degrees.
35. 35. EliminateAdd all the sides, A because the The correct then subtract angle is answer is B. from 360. Copy in obviously obtuse. your notes: Angles of a quadrilateral measure 360 degrees.
