2. A poll predicts that candidate A will receive 48% of the total votes in an election. If 60,000 people vote in the election, how many votes does the poll predict candidate will receive? f. 28,200g. 28,800 h. 31,200j. 32,800 4.4 warm-up 9

3. 6.1 Classifying Quadrilaterals Pardekooper

4. You will find the length of the sides of a parallelogram.

5. Lets start off with some definitions. Parallelogram - opposites are parallel Rhombus - parallelogram with 4 congruent sides. Rectangle - parallelogram with 4 right angles.

6. Lets start off with some definitions. Square - parallelogram with 4 congruent sides and 4 right angles. Kite - quadrilateral with 2 pairs of adjacent congruent sides and no opposite side congruent. Pardekooper

7. Lets start off with some definitions. Trapezoid - quadrilateral with exactly one pair of parallel sides Isosceles Trapezoid - quadrilateral with exactly one pair of parallel sides and non-parallel sides congruent Pardekooper

8. Lets look at an overview Kite Pardekooper

9. Don’t forget the following: Slope: y 2 -y 1 x 2 -x 1 Distance:

10. m = (y 2 - y 1 ) (x 2 - x 1 ) m = (-3-1) (5-2) m = -4 3 Find the slope given the points {(2,1), (5,-3)} Pardekooper

11. Find the slope given the points {(3,5), (-1,4)} m = (y 2 - y 1 ) (x 2 - x 1 ) m = (4-5) (-1-3) m = -1 - 4 = 1 4 Pardekooper

12. Two lines are parallel if and only if they have the same slope. example: Pardekooper Two lines are perpendicular if and only if their slopes are opposite inverses. Pardekooper

13. Pardekooper Find the distance between two points. (6,6) and (19,6) 13 Pardekooper

14. Classify the following: A(3,5), B(7,6),C(6,2), D(2,1) Pardekooper Now lets work a problem Graph the points. A B C D Connect the dots In the order They are Written. Now find the slopes. 1 / 4 1 / 4 AB || DC 4 / 1 4 / 1 DA || CB Opposite sides are parallel But not perpendicular so no right angles So that makes it either A parallelogram or A rhombus Find the length of the sides.

15. Classify the following: A(3,5), B(7,6),C(6,2), D(2,1) Pardekooper Now lets work a problem AB =  (7-3) 2 +(6-5) 2 =  17 BC =  (6-7) 2 +(2-6) 2 =  17 CD =  (2-6) 2 +(1-2) 2 =  17 DA =  (3-2) 2 +(5-1) 2 =  17 Rhombus

16. Here comes the assignment.
